Hey there, I am new to this breed and hatched out 12 SFHs in February which appears to be an even split of 6 pullets and 6 cockerels. Can someone enlighten me about the faults that arise when two crested are bred together? What does vaulted mean? What are the problems that will arise? One of my pullets is VERY crested (looks like a Polish) and she seems a bit dim. Is it undesirable to have that in the breed? Thanks!
When breeding crested to crested, the result can be a huge crest or a vaulted skull. A vaulted skull can leave them vulnerable to being pecked or getting brain damage. Too big of a crest hampers their vision so they are more open to predator attacks. I would not breed crested to crested. Post some chick pics
