Hello! I have four chicks that I hatched from eggs that should all be some sort of mix of Easter egger and true blue whiting, and am trying to guess gender at 7 weeks even though it seems like a fool’s errand. The eggs we got were clearly from a couple different hens, but the white chick and the brown chick both hatched from a pair of larger, pale blue eggs and the two black chicks hatched the next day from a pair of smaller, blue-green eggs. The white and brown chick have stayed consistently larger than the black chicks but all seem very healthy. That said, I think the white chick and the brown chick are actual siblings, which is why I want to use the comb size on the white one to say it’s a rooster as compared to the brown chick. The white chick has had a comb (which I guess is already red, though I’m not sure how red qualifies as red) since it was two weeks old, and the other three are only just in the last week (at 7 weeks) developing more visible little brown pea combs. It’s hard to get good pictures of them but I’ll include the better ones I have. Thinking I have a cockerel and three pullets but I won’t be surprised to find that i’m off the mark. Thanks!
