I have a flock of 14 free range guineas about the same age. They were all hatched out between March and June of this year. When I would introduce the new keets the older ones would chase them, but as they got older, everyone assimilated and joined together as one flock. And they stayed this way for months. Until about a week ago, two have been ostracized from the rest of the flock. The two stay to themselves and when they get near the flock, they are chased away by the other birds. I know guineas are peculiar birds, however I was hoping some one could explain this behavior. And if there are any suggestions for making the flock whole again, that would be great. Because the two lone guineas are much louder than usual (I don't think they like the new arrangement) Thanks!!
