Dozen green olive egger hatching eggs. I mostly have back crosses at the moment but do have some first gen olives.

Dark gene black copper Maran Roos over olive egger hens. BC1 - BC4

Any hens that hatch from these eggs can lay brown or green-dark green eggs

Most of the chicks this year have been hatching out black or gray. Some have fluffy cheeks(like an ameraucana), some have puffy heads(like a legbar), some look like a regular black copper Maran. Some have a little of everything
