Does anyone else's Guineas buck-wheat and get LOUD after dark for no apparent reason? I have 9 guineas, and all but 1 are less than 6 months old. I'm not sure how old "Blue" (the older one) is as he came with the house and former owner didn't have a clue either. My guineas are inside a pen at night and are well protected from predators, so I know there isn't anything IN there to get them stirred up, but several times during the night all the girls will start buck-wheating. This will go on for anywhere from 5 - 30 min then they will quieten down. Some nights they do this several times a night, other nights its only once or twice. They don't get down from their roost during this, the girls just get loud for a while. Is this normal?
