I am on the hunt to expand my flock of chickens, But I am finding that I do not want to just trust people when they say they have all hens, as I went to one house and from what i saw they all had combs like my Buff Roo. Are the combs on some hens big and dark red like roos? I also notice my roo has big hanging red flaps under his chin that my hens don't have. So now I am looking to expand into different breeds of chicken, I have all buffs, one white amerucana and one chicken I don't even know the breed.(Picture of her, kinda blurry) she was a rescue and is in rough shape, but getting better. I know this is probably covered on this forum somewhere, I just can't figure out where! Please, any help to educate me more or point me in the right direction would be greatly appreciated!
