I have a BR roo and RIR hens. I set some of their eggs, only 4 were fertile. Day after Thanksgiving They hatched all 4 of them. Yea! Ok now the question. These chicks have black legs. I know for a fact that it was BR roo over RIR hens as none of the rest of my girls are old enough to lay yet and they are in a separate run where the roo cant get. I think maybe my BR is a mix I got him from a lady selling babies raised him from 10 days old. The thing that makes me think he is a mix is he has some green tail feathers and a little gold in his hackles. I have another BR roo and he is just black and white no other colors in him. Here is a pick of Lindy where you can see his green in the tail feathers and a pic of one of the babies with black legs. What do you all think?
