I purchase some black production chickens from a local country store and was wondering if anyone could tell me what the crosses might be. The one which I believe to be a rooster had white under its butt and on its chest when it was little and now has white in its chest feathers, while the other one is mostly black but also has some white in its feathers, don't know if the last one is male or female yet, thinking its another male but its crown is actually almost black so couldn't really tell by color.
