Hi! This is my first time with chicks and of my three chicks, I have one that I am struggling with. They are 4 weeks old. #1 looks to be a clear Roo, large funky comb and slow to feather. He is also slightly bigger than the other two #2 I believe is female. Has the smallest comb and feathered out a bit faster #3 Has Gender identity issues. He/she feathered out slower, but doesn't seem to have a large comb. It is very slightly bigger than the suspected girl, but a lot smaller than the suspected roo. He/she is also smaller than the suspected roo. Any pros that can help?
