I have 3 guineas. I had 4, one was killed by a dog. 2 are from the same clutch and are attached at the hip. The other (and the deceased one) were from another clutch, about 2 weeks younger. I think the pair are both male and the outsider is female. She walks around calling"buckwheat" a LOT. The other two are relatively quiet, usually just kind of squeaky mumbles most of the time. One of the pair will sometimes chase after the female, but it seems more like they are chasing her away then chasing after her. Looking at the wattles, it seems the two are both males and she is a female, but I'm not sure if that might be just because she's from a different clutch.
