The girls start getting red combs when they are about to begin laying, around 5 months. The big comb on the one you have means it is more than likely a boy. Boy's combs get red quite young.She is a beautiful girl....I am so confused. Our buffs our about 3 1/2 months old and we have one with a comb and waddle like this as well but the other 3 do not, only small combs. Everyone tells me she is a rooster, but I don't see the tail feathers. When do the girls start getting larger, red combs and waddles? Thanks.
