From what I've been able to tell, is that Wyandottes (hens or cockerels) all get redder and larger combs much faster than other breeds. The hens feather out faster in the tail and their lacing pattern is all over. Males don't really have the lacing pattern on their backs. Looking from a birds eye view down on their backs, the females will have a very obvious lacing pattern where the boys will not, or it will be very muddled.
