The chicks are 11 weeks old and I seem to have a large number of roosters. There's only 1 I'm sure is a hen. These four I'm unsure of, though I'm hoping they are hens. These 3 black and whites in the front are in question. Their combs are a little pink, but not nearly as big or red as the known roosters. This brown and black one. It's comb is also not as big and red.
