I have a bunch of chicks that were hatched by a broody hen. The adults we collected eggs from were White Orp's, Barred rocks and some red sexlinks, the rooster was a Wyandotte cross between a Gold laced hen and a BLR roo. We've got 2 chicks that at 4wks old are Black with back legs/feet and beaks. Will these colors stay as they mature? We assume that the black chicks came from the Barred rocks as well as the two gray chicks we have. But none of our chickens have black legs/beaks. do barred rocks have black chickens in their family tree?
