I was aware of the defects in this particular group. It would probably be easier to get Cuckoo Marans hens and breed until I get a replacement cock, if I can't find any Birchen that I like? I am pretty isolated so new genetics won't happen soon unless I am lucky to be honest. Are you saying I would have to destroy my whole flock and start again based on a cosmetic flaw? Or can I slowly breed it out, as I intended to do?
