I have some chicks that are wyandotte crosses. HOW do I tell the roos from the pullets? Do you still end up with a larger redder comb sooner?! All the other chicks with single combs are starting to show their sex pretty clearly. I am wondering if these are maybe pullets since their combs are pretty much nonexistent and still very pale. I don't have pics - just hoped someone could fill me in that has these comb type birds.
