Is it difficult to breed out comb disqualifications? Or will they carry over to all the children? For example, I have a Belgian d’Anver cockerel who would make an excellent breeder but his rose comb spike looks to be splitting into two spikes…will all his babies have this issue or can breeding with a good hen help get rid of it? Should he be a cull or can I use him without compounding my problem in more generations?
