Same chickens, different combs

[familyfarmer4]

Single combs are recessive in wyandottes indicating both parent birds of your bird had the genes. When breeding is about quantity over quality (ie hatchery stock) selective breeding is not applied so you see these out of standard characteristics more often. A good breeder would not breed single combed birds and would remove parent birds from breeding as well (they would know paremt birds due to careful breeding and revords)

This makes sense since I got these as chicks from a large hatchery. I don’t breed my chickens so the combs don’t matter to me.
