I have 10 chickens that are about 4 1/2 months old. At about 4 weeks old one of the Buff Orps had a much larger and reder come and waddles. But looking at him? now I do not see the obvious saddle hackels that are present in most roo chickens. Are BO just a different breed and the roos do not vary that much from the hens? Also...he? has not crowed once! Second, of the three brown leghorns...two have much larger combs than the rest but the tails are still "short" and looking nothing like a traditional rooster. Should leghorn roos over 4 months have OBVIOUS rooster tails? Thanks gang.
