In GENERAL, at what age do Black Australorp Cockeral's combs and wattles begin to start turning red? I have 4, 5 week old BA's who's combs are very delicate and small, their wattles are just now starting to slightly show. The combs have the tiniest bit of color although very very pale. All their shanks are exactly the same size as the others. I got them out of the pullet bin from the feed store. Any information would be helpful.
