I have 8 guineas, 5 months old, hatched and raised by a bantam hen. There are 6 males and 2 females. One of the males keeps to himself because another male runs him off from the group. He won't go in the coop at night to roost with the other. He sleeps on top of the coop, even in snow, sleet and freezing rain. He can't even eat with the others. It's sad Is he doomed to be an outsider?
