You know, MY 7 month old EE/Dorking roo "Mully" is the same - tiny comb, has yet to crow ... when I got him at 4 months of age I thought he was a hen because he didn't have any sickle feathers yet. Now, he is clearly a rooster (and so very sweet, a real cuddly guy) but doesn't crow either. On the plus - an excellent lead guy who watches his girls very carefully when they are free ranging and rounds them up for me and brings 'em back into the coop. So I guess the question is: Do EE roosters mature later than other breeds????
