I have four female and one male guinea. They are probably just a year old now. They have recently taken to hanging out in the weeds along the edge of our woods. There is also a strange new sound coming from them. Its not the typical "buckwheat, buckwheat!" call of the female. Its different. I actually thought it was a distress call at first because as the female was making this sound from the weeds the male was frantically running back and forth in the field in front of her. All of my guineas have been accounted for at night until recently, one is missing. During the day the male is standing guard along the edge of the weeds. I'm wondering if one of the females has a nest down there and could she be setting?
