In May I already had three Wyandotte chicks: one rooster and two hens. After 4 weeks or so, I could clearly see that one of them would turn out to be a rooster. He already showed a bigger and bright red comb, whereas the other two had a narrower and pale comb. The rooster is now about 11 weeks and has been crowing for some time already. This bunch of chicks today just seem more difficult to determine. I guess I'm the impatient type.
