There are quite a few breeds out there that look grey, so if you’re looking for one of these beautiful birds you have quite a few options to pick from!
Most have feathers that are composed of various shades ranging from almost black to pale silver and others are more uniform or even extravagantly patterned.
Each feature helps makes up one of the grey chicken breeds.
Chickens have complex genetics when it comes to feather coloration and there are many different ways to make one that appears grey.
However, not all of these breed true, so their chicks could end up in a variety of different colors.
What Makes a Chicken Grey?
Grey feathering comes about a few different ways and is usually based on a black-colored bird.
Most often if you see a grey chicken breed it will technically be blue or lavender, but some are blue laced, blue mottled, or splash.
There are even color combinations that can look rather grey, like the fawn silver duckwing!
Birchen is sometimes called grey in Japan, which can further complicate things for you, and some breeds have grey in the name or variety name.
One of the most common types of grey chicken breeds is called blue. Blue chickens are defined by their fairly uniform grey coloration and are not supposed to have other colors “leaking” through.
Many of these blue chickens might have a darker shade around the edges of their feathers and quite a few have noticeably dark heads and necks.
Blue is controlled by an incomplete dominant gene acting on a black chicken. One copy gives you a solid grey appearance while two give you a white or pale grey bird with black or blue splashes of color.
This second (the homozygous blue) is called splash. This means that when you breed two blue chickens together half of the chicks will be blue while the rest will be either black or splash.
Lavender, also called self blue, is another way to make grey and it also requires a black-based bird. It is a recessive gene, so the chicken needs two copies to appear grey.
Since the birds have to be homozygous to express the color dilution you will always get lavender chicks from two lavender parents!
Good-looking lavender chickens can be difficult to breed because this gene is known to cause brittle feathers.

Grey Chicken Breeds in Conclusion
As you can see, grey chicken breeds are a pretty difficult color to figure out when it comes to chickens! There are a lot of different genes or gene combinations that result in a bird that appears grey.
Your best bet, if you want a flock of grey-colored birds, is to pick a popular breed and look for a blue variety. If you want something a little more complicated, but more of an elegant grey, you can track down lavender.
Keep in mind that color does not make a chicken and you should focus first and foremost on the type and quality of the bird itself. Many exhibitions, like grey chicken breeds, lose the characteristics that made them great when breeders stop focusing on the big picture.
