Hi, new here, my name is Darren. I have an interest in sex link chickens. One link is love to know if it works in a RIR rooster x cuxkoo Brahmas and has anyone tried this. I thought the roosters might make a nice table bird. I know it won’t be a super high egg prouction bird but thought the RIR might increase that. Anyone done this? Also I know a dark Brahma is theoretically a silver gene bird but would hens with a rir rooster make a sex linked bird?
