At what age do pullets begin getting red in their combs? I know that early red in the comb & early wattle formation indicates a roo, but when is it to be expected in the pullets? It has to happen sooner or later, and it would be good to know when to stop worrying that 'it could be a roo'. My standard chicks are now nearly 6 weeks. One of them seems to have some red in her comb this morning. It isn't (yet) very dark and seems more pink, but is more colored than the other pullets, who are still mostly yellow. She doesn't seem to be particularly rooster like in having bigger legs or feathers. Just curious.
