I have two roosters who have a brahma for a dad, but their original owner is not sure of who their mom was- she said it was one of a few utility breeds, maybe white rock? perhaps RIR? or a leghorn? i think those were the choices she gave me- do you guys have any ideas? I'm going to let him breed with my Barred rocks and favorelle, and EE's for some mutt chickens that I'm hoping will be a halfway decent size for meat and maybe have decent egg production. The Black&white one is Charlie- and he has some barring on his black tailfeathers. The White one has a faint beige barring on his body and a slightly taupe color to his tailfeathers. He's Latte. Any ideas on what they are mixed with?
