What is an Olive Egger Chicken?

olive egger henHeads up! Olive Egger chicken is not a breed recognized by the American Poultry Association, but instead a hybrid or a cross of two breeds — specifically, a blue egg layer and a dark brown egg layer. 

They sought them after for their beautiful olive green colored eggs and sweet disposition.

These birds can be a great addition to your flocks for several reasons. 

But before we discuss why this breed is a must-have, join us as we dig deep into their eggstraordinary history. 

What Makes An Olive Egger Chicken – Their Eggstraordinary History

As mentioned earlier, Olive Egger chickens are produced by crossing a brown egg layer and a blue egg layer. 

The blue egg layers that can pass as Olive Egger chicken parents include the following breeds: 

On the other end, the brown egg layer breeds that can be used to produce Olive Eggers are:

If you’re wondering how this cross-breeding began, well, the craze started in around 1842 when Chinese chickens were brought to and crossed with local breeds in England. 

This phenomenon made farmers experiment in crossing different varieties with specific traits. Due to the egg-citing discoveries, many more scientists became interested in this process and joined the bandwagon. 

Since then, they learned how to cross-breed to have more active, robust, and adaptable chicks. This trial and error process was the reason for Olive Egger chickens’ birth. 

These birds are one of the most exciting and are in demand chickens in the poultry department, thanks to their iconic olive green eggs. 

Olive Egger Chickens’ Breed Standard and Appearance

Since Olive Eggers come from different parents, their appearance varies; some have pea combs, feathered legs, and muffs, while others may not.

They can also have different plumage colors, and they’re so diverse and unpredictable. 

But sometimes, Black Ameraucana crossed with Black Copper Marans will result in either a solid black chicken with Ameraucana cheek puffs or a chick with feathered feet like the Marans. 

An Olive Egger’s body is usually stocky, and the roosters may weigh around 7 to 8 lbs while the pullets weigh about 6 and 7 lbs.

That means they’re just medium-sized chickens that won’t produce much meat as other breeds. 

How do you tell if my Olive Egger is a rooster?

If your Olive Egger is from a Cream Legbar and Black Copper Marans, you’ll know if it’s a male at the time they have because males have white dots on their heads. 

On the other hand, Olive Egger hens will have either solid black with a crest or black feathered with bronze shade in their hackle feathers. They feature a range as well. 

On the other end, Olive Egger roosters boast a barring, and they may have or may not have a crest.

Olive Egger Chicken Temperament and Disposition

Even if Olive egger rooster and hen’s temperament vary depending on their parent fowls, these birds, in general, are friendly and docile.

But the best way to determine what your Olive Eggers’ disposition will be like is by knowing their parents’ temperament.

If their parents are gentle and have a good disposition, they will likely inherit that. For example, chickens with Welsummer parents are more likely to be intelligent. 

And parents with calm and friendly personalities will likely produce chicks with the same temperament. That can help you see what breed combination will work best for you.

However, some poultry owners find their Marans standoffish and their Ameracaunas skittish.

But the offspring are friendly, so it seems that some have retained the good qualities of their parents. But of course, they can also be pretty talkative and chatter quietly.

Olive Egger Chickens’ Egg Laying Capabilities

As its name suggests, Olive Egger chickens lay vibrant olive green eggs, but they can still vary depending on the parent fowls. Some produce blue, green, brown, and even pink eggs. 

When you cross two breeds, the combinations aren’t 100% predictable. That’s why there are some differences in their offspring’s colors. 

The inside of their olive green eggshell is usually bright green, while the outside looks brown with a translucent coating. 

The green shade of their eggs can be anywhere from bright green to brown hue. So, having Olive Eggers can surely make your basket more colorful.

The eggs of these chickens have vibrant green colors, thanks to their dark shades of brown.

Olive Eggers produce 4 to 5 large-sized eggs per day and about 150 to 200 eggs per year. They start laying at a young age of 5 to 6 months.

The average could be slightly higher if they have Ameraucanas in their blood. Some breeders even find them more consistent egg layers than Ameraucanas. 

They have a high chance of survival even in cold climates because these are cold-hardy chickens that can also tolerate heat. 

Egg color: Olive green, but sometimes blue and pink

Egg size: Large

Laying habit: 150-200 

Meat Production of Olive Egger Chickens

Olive Egger chickens are excellent in producing colorful eggs, but they’re not the best chicken breed for meat production. They don’t provide much meat, and they aren’t known for it.

However, hybrids that carry Marans’ blood who have more giant roosters that weigh around 3.4 to 4 kg can give more meat. That’s because their breed is usually larger than Americaunas. 

So, if you have too many roosters as most breeders do, a few cockerels might flatten up your fridge nicely.

How to Raise Olive Egger Chickens

Feeding and Meeting The Nutritional Requirements

No matter what the breed of the chicken is, you always need to provide the best chicken feed for them to grow faster and optimize their egg production.

As for Olive Eggers, these birds need a chick starter that meets their needs right from hatching to their 16th week of life. 

Their needs will naturally change as they grow older, and you will need to transition them into a complete laying feed a few weeks before they start laying eggs.

They also need a calcium supplement to ensure their olive-green eggs will be solid and thick-shelled. 

Housing and Fencing for Olive Eggers

These chickens don’t need a massive space to thrive. A 4 square feet space per bird will be sufficient if they’re in a coop.

But if you prefer to put them in a run where they can free-range, the recommended space is 10 square feet per bird. 

Diseases and Health Issues of Olive Eggers

Olive Eggers are healthy birds that aren’t prone to common chicken health issues like diarrhea, coccidiosis, and fatty liver hemorrhagic syndrome.

However, you need to watch your birds if they have scaly leg mites. Most birds are susceptible to chicken mites, and they’re so small that they’re hard to notice. 

The next thing you’ll see is your hen’s coop is full of destructive mite and itchy, miserable birds. 

These mites are like vampires that live on your chicken’s body and feed on their blood. They seem like tiny ticks that live, reproduce and die within about a week.

But in that short period, they’ll feast on your Olive Egger’s body like crazy. That’s why suffering birds peck and scratch at themselves. 

Signs of Mite’s Presence : 

Their symptoms under mite attacks include feather loss, scabby legs and feet, pale comb, and reduced laying.

And you can only see mites in your Olive Egger’s body if you’d thoroughly check while they spread their wings out and their skin looks scaly, red, or inflamed. 

How to Get Rid of Mites:

You can treat chicken mites by dusting all your Olive Eggers with diatomaceous earth. Adding a cup of the diatomaceous world into a sandbox of dirt and sand where chickens can dust bath can also help. 

Others prefer to dispose of the beddings or burn them after cleaning the coop to kill the mites. 

But there’s also a natural remedy: the neem oil that disrupts the life cycle of mites, lice, ticks, and fleas and nourishes the skin.

You can apply it directly to your bird’s skin or add two teaspoons of the oil in a spray bottle with apple cider vinegar and water and spray it into every nooks and corner of the coop.

Of course, you need to clean the coop and move your chickens while doing that. 

Most mite killers are dangerous to other animals. But if you live in ore temperate areas and need more robust solutions, Permethrin might be the safest way to go.

It’s available in both liquid and powder form, and you can apply it directly to your Olive Egger’s skin use it as a coop spray. 

Now let’s get into the scaly leg mites. 

Remedies for Scaly Leg Mites:

One of the signs of having scaly leg mites is if there’s thick skin on the top of their feet.

These mites can live even in winter and can be disturbing for your birds because they burrow under their skin and make the scales on their legs and feet stick up. 

It can be painful for them because these parasites bite your birds and feed on their blood. 

One way to remedy this situation is to spray your birds with a garlic juice mixture that can 100% kill mites over 24 hours. Just mix the following to get the right solution:

  • 10 ounces of water
  • 1 ounce of garlic juice
  • and one teaspoon of a combination of commercial oils like bay, clove, coriander, spearmint, lavender, and thyme

Just mix them and spray them into your bird and their coop every other day for around 2 to 3 weeks if your coop is infested.

And put more under their wings or around the vent to make sure you get rid of all of them. 

You can also use it as a preventive solution and spray it bi-weekly on your birds and their coop. 

If it’s not available, you can use warm soapy water to wash your Olive Egger chicken’s leg, then wipe it with a washcloth in a gentle manner.
