I have 18 guinea keets which I hatched out over the last several months. The largest are ready to go out free range but I am not sure how to introduce them to the flock of 7 adult birds which I already have on free range (but sleep in my chicken coop with the chickens). With the chickens, I would keep them in a separate open shed in a cage for week or so , so the other chickens could get used to them. Should I do the same with the guineas? Anyone had any experience with this situation?
