The Sapphire Gem Chicken: The Complete Info Guide

Also known as the Sapphire Blue Plymouth Rock or Blue Plymouth Rock, the Sapphire Gem is all the rage for novelty and specialty chicken fanciers. Scouring the internet for information on this rare variety will most likely lead you down a dead-end road or to the local jewelers’ websites. There is conflicting information on this variety of chicken, but one thing everyone seems to agree on is that this bird is a new favorite.

The Sapphire Gem is not an actual breed of chicken, and not recognized by the APA. Most hatcheries that sell this little gem are vague in their descriptions, and that’s probably because it’s a new variety of chicken. In fact, this chick can only be purchased from a handful of hatcheries, and it even appears as though one hatchery has the name Sapphire Gem trademarked

What we do know about this mysterious chicken is that the Sapphire Gem is a cross between heritage and hybrid chickens and was developed in the Czech Republic. This treasured bird is said to be crossed with a Blue Plymouth rock and a Barred Plymouth Rock.

Since the popularity and excitement over the Easter Egger has begun to dwindle, many chicken lovers are rejoicing at the addition of another fun chicken to add some spice to their flock.

The Sapphire Gem is a sex-linked chicken variety of chick, which means that their gender can be determined shortly after they hatch just by observing the colors of their feathers. This trait is caused by cross breeding chickens.

Another important note about the bedazzling beauties is that they do not breed true. If you are new to chicken lingo, this means that if you breed two Sapphire Gems, you will not necessarily get another Sapphire Gem. 


If you love exotic colors in your flock, the Sapphire Gem will catch your eye with their lavender and blue feathering.  The roosters are typically blue with a white dot on his head while the hens are mostly blue with a necklace-like ring of gold or grey adorning her neck. There are some that go gaga for these colors, and some who seem to turn up their noses. So, it’s safe to say that reviews on appearance seem to be mixed.

The Sapphire Gem has an upright appearance, similar to that of a Plymouth Rock, due to its genetics and she sports a single comb atop her alert little head. 


The Sapphire Gem is a medium-sized chicken. She won’t tower over your Easter Eggers nor cower under the Brahma. They are a middle-of-the flock size and can hold their own amongst a mixed flock of chickens. 


Large, brown, eggs are the Sapphire Gem’s specialty, and it’s a common misconception that this chicken lays blue eggs because she is often confused with the Sapphire chicken (a small white bird that lays bright blue eggs). 

This little engine-that-can produces year round, and has been said to lay up to a whopping 290 eggs per year! So, as you can see, her purpose is production and is not typically used as a meat chicken. 

Cold Hardy

The Sapphire Gem chicken does well in all climates with reports of withstanding cold winters with grace and without decreased production. As with other single-combed breeds, it is wise to protect the Sapphire Gem from frostbite during the colder months to prevent their combs from falling off near the end of the season. 


Sapphire Gems are wonderful free-range candidates if you like to let your chickens run free. They are excellent foragers and have no trouble finding the tastiest morsels in the yard. While they are a calm variety of chicken, they are also alert and aware of predators, which makes them even better off if they have the run of the yard. 


Raving fans will happily tell anyone who will listen, how incredibly calm and docile this chicken is. Photos are circulating of the Sapphire Gem calmly sleeping in the arms and hands of their adoring owners. They are said to love to cuddle and are one of the sweetest varieties of chicken for the kids.

While this chicken is the new “It Girl” on the scene, there is still little known about the origins and where to obtain her. You can bet that the popularity she has already gained will only continue to grow, maybe even as fast as that of the Easter Egger!

      I have gone to this hatchery and they are very good. It was a great alternative side the last group of chicks I had delivered via the mail 5/6 were DOA.

  1. Ad says

    Do chickens quit laying when it gets so hot outside ? I haven’t gotten any eggs the last 3 days and it finally got in the 100s just this week.Or could there be something else ?

  2. jimmy says

    I have a mixed flock of brown egg layers and the sapphire gem hens lay extra small eggs , pretty to look at but poor quality eggs

    • Rachel says

      Really!? I just got two Sapphire Gems this spring and they were the first to start laying. The first layer was only 4.5 months old when she started and from the beginning (besides two fairy eggs) she’s layed large eggs. The second one started laying at 5 months and she is also lying large eggs even though she’s only been laying for about 2-3 weeks. I was honestly surprised with how big the eggs were in such a short amount of time. I’ve been very pleased with these birds so far.
      That’s such a shame that you haven’t had the same experience with them.

      • Jill Durham says

        I have one sapphire gem. She is an excellent layer, good natured, and very social bird. In our flock she is a star! Her eggs are large brown eggs second to none. ?????

    • Chicken mom says

      When your Saphire Gem Chickens first start laying eggs they will be smaller but then they will get bigger as they continue to lay eggs

  3. Birdie Mama says

    My sapphire gem is the best bird in our mixed flock (buff orpington, 3 easter eggers), and she’s been laying everyday since 5 months old (big eggs and double yolks ). Anyway she’s a fun smart bird that doesn’t need supervision outside. I know all chickens are different, maybe we just got lucky, but she acts like a pet. I’d recommend the breed to anyone starting out .

    • Karen Scheffter says

      I have three sapphire gems, they all started laying early, all eggs are jumbo size, with a significant amount of double yolks. Extremely gentle and comes when called. Love these girls!

  4. Rob says

    I have 10 I hand raised thinking the would be sweet like everyone reported. Nope mine keep their distance don’t want to be around any human once grown. except when I have food but even then keep their distance

  5. Laura Sinkbeil says

    It’s my first year of raising chickens and I got an assortment of 10 different breeds. “Silvie” my sapphire gem is my favorite in the flock. She always approaches me, had beautiful brown eyes, and if I figured out which egg is hers right, then she’s laying large light brown eggs well starting around 22 weeks. She is my largest hen, and probably a little overweight.

  6. PA Breeder says

    Why is Catch a tori farm breeding Sapphire Gem to Sapphire Gem? They are not breeding the Breeders that create the sapphire Gem.


    i ha two sapphire gems, one is like my little baby, the other not as close but getting there. beautiful girls

  8. Summer says

    Love them! I have two 1 is super friendly (Stormy)she’s been trying to gain higher ground since she was tiny so now enverytime I bend/kneel/squat down she hops right onto my back making her way up to my shoulder as I stand up I believe the leader amongst the 9 others. They’re both very intelligent that’s for sure, Breezy the shyer of the 2 gave me my very first egg ON MY BIRTHDAY! The very nyday Stormy started and they’ve been laying extra large cream/light tan colored eggs since. They consistently lay, Breezey had given me a number of double yolkers that looked like emu eggs!

    Amazing breed ! Just hope not too amazing to be true only time will tell with this new exciting beautiful breed ?

  9. Rebecca Choate says

    I purchased 4 Sapphire Gems from a friend laying size. One consistantly lays large light brown eggs, some double yokers. The other 3 don’t lay every day. May only get 1 or 2 eggs a day. They get plenty of layer feed and corn a day and free range a short time due to predators. Don’t understand why three of them don’t lay much. I live in S. FL, so their not exposed to cold much. Any ideas? Am incubating some of their eggs. Don’t know what to expect, but hoping for some large eggs.

    • Rebecca Choate says

      The sapphire gems were bred by a white crossbred golden comet rooster and I wanted some babies that would grow to lay more large brown eggs. Waiting to see what or how many will hatch. The hens are beautiful, docile, and friendly.

  10. Kate says

    I recently hought 9 baby chicks that are sapphire gems.. this morning 1 had passed and another is very weak and on her way 🙁
    I have them in the house right now with large cedar chips and heat lamp.. them fresh water and water with probiotics and electrolytes added… originally the water was well water as we are out in the country so I have switched it to bottled hoping that was my problem. Was giving them chick grit and going to look for something different today as well in case it is the food.. the other 7 seem to be doing well so maybe its just you lose some… any suggestions?

    • Lisa says

      I’m not sure about the use of cedar chips, only pine. But change bedding every other day. And they can get Coccillia. Not spelled correctly, sorry. But my grand mother always said to add a tablespoon of apple cider vinegar to one quart of water. 4 tablespoons per gallon. Good luck.

    • bob says

      The cedar chips may be the problem . The aroma of the chips are causing lung issues for their tiny lungs . Cedar is good for adults dogs , to help control flees and mites , but can cause severe issues with smaller animals. Also have a area of sand or dry loose dirt for the chickens to take a dust bath . They love doing this , and it helps control mites as well .

    • Jennifer Shelton says

      Replying several months later, so too late to be of help. Noticed you said Chick Grit, but that is not feed, & is for chicks older than 2 weeks. Grit is given to aid in digestion when chickens can’t free-range & get it themselves from dirt. Also, we’re on well water, & my chicks are all fine. I use Hydro Hen every other day in it. My SG’s are so sweet & curious!

    • Emily says

      Chick grit is not food. It is tiny little pieces of gravel that help them digest their food. There is no nutrition in it. On my bag, it said to make sure that they are not eating too much when you first introduce it at two weeks along with their actual feed. If you are just giving them grit, then you are just feeding them rocks.

      And both of my rabbits died shortly after introducing cedar bedding to their cages.

  11. Jennifer says

    Any recommendations where I can find Sapphire Gem chickens for purchase close to Colorado?

    • Teresa M. Slater says

      We got ours from A farm store, they get their chickens from Hoover’s hatchery in Rudd, IA

    • Nancy says

      We ordered from tractor supply. They’re supposed to ship wherever and come from Hoovers Harchery in Iowa.

    • Hannah says

      I purchased some in March through Tractor Supply online. I never thought I would love a chicken, but I love these, lol.

  12. Kayla says

    What are your thoughts on the sapphire Gem rooster? I realized I have one and it was sexed wrong… it is already starting to crow but I was curious if it will REALLY crow or sound like the one on your video 🙂

  13. Konni says

    I have sapphire gems, white leghorns, ISA browns, and golden comets. I know that several of those breeds will not breed true. I would like to hatch some eggs for future hens. Do you have a suggestion for a good rooster breed to mate with them?

  14. Maria says

    I have a Sapphire Gem that I got just by chance. She is my favorite! She loves sitting on my lap and is super smart and social. We get one very large egg from her every single day without fail. She’s a good girl. Wish I had a dozen more like her.

  15. Brenda Albee says

    I have 10 Sapphire Gems that are 8 weeks old. I love them they are beautiful and friendly. My grand daughters love playing with them

  16. Judi Adcock says

    I have 6 SG (one week old) and have ordered 5 more day old chicks that will be in Friday. Can I go ahead and mix them together since they are so young or will I have to separate them until they get use to each other?

  17. Bea Licorish says

    Go online and check with Hoover Hatchery. I just purchased and had shipped 15 chicks from them two weeks ago. Three of the 15 are Sapphire Gems.

  18. Don says

    I bought 10 hens from Tractor Supply (Hoover Hatchery) in April. Now at three months old they’re all hens and healthy. Very friendly. Several hop on my shoulders. Several like to have their backs rubbed in the mornings. They don’t try to run away when we let them out of their run. My grandkids love to cuddle with them and feed them meal worms.

  19. David says

    hi, I got 9 sapphire gems. They are now 4 months old. I have little combs and big combs, they already laying but I can’t figure out which ones because they like to lay at 6am. Those who have sapphire gems hens how big are their combs?

  20. Heather says

    My sapphire gems are quirky. One likes to go off alone to sleep. She’s the last one in the coop and often we find her in the milking barn alone in the dark because she doesn’t want to go inside the coop at all. They lay huge cream colored eggs. They never had pullet sized eggs. Shockingly big eggs – many double yolked! Lol ?

  21. Jennifer says

    I have had our sapphire gem for over a year. She was first to produce eggs. She was first to do anything. (They are very smart) Her eggs are giant!!!! She always seemed to be separate from the flock. A couple of months after Our sweet dominant hen passed away, she started to peck me she learned that was not allowed then I introduced four 6 week old babies. she started to try to kill the babies. I took her to live with an older flock of chicks that were bigger than her but only 5 months old. She would chase them but not hurt them. I brought her back home after two days of this and have kept her away from the babies. Generally, this chicken has been sweet until now. She is smart so I am trying to teach her to be sweet. The other two adult hens are also standing up to her and telling her to be nice. I’ve only had chickens for a year so this is all new to me. I spend at least a half an hour a day with them and I try to teach them I’m the head of the pecking order. That way, as the flock changes there will be stability in the pecking order. This may be foolish but the only other option is to eliminate the sapphire Gem.

  22. Justin says

    Does anyone know what kind of winters this chicken can sustain? The article says they’re cold hardy, but doesn’t give any temperature or weather examples. I want to make sure I get a heating element ahead of time if I need one.
