Take better head shots. If they are only 4 months old and already have small red combs I can almost assure they are cockerels. My pullets do not develop a red comb till they are a month or so from laying which is normally 8+ months old. Also I just think they look male .. .Are u sure they are cockerels and if u want me to capture anything to make sure because some people tell me they are pullets and others tell me that the both are cockerels . Would anybody ensure me what gender they are ????? !!!!!!
As for breed I have only seen beards on Thai. Maybe they are a mix, I don't know.
I say take good head and leg and feet pics and post them.
