long story short. I bought BCM eggs hatched them raised them and now hatched some of the eggs i got from them. only one little problem i am getting some yellow chicks. I guess they will be wheaton marans. so i am guessing my parent stock are not pure black copper marans. so do i need to cull these birds and start over? I have no other roo's only my black copper marans roo's. thanks I am adding a photo of one of the chicks. it has a blue tint to its back.
