Totally unrelated question, but I've four FBCM chicks, 3 roosters with pink combs - huge pink combs. And what looks to me like a pullet as her comb is very small, but it's also dark-colored - almost black. What's up with that? Is it normal? They're about 4 weeks old, from a blue copper marans roo over black copper marans hens. This one with the dark comb was also slightly bluish at a day old - where the black meets the white on the down.
