Is there any chance that my adult guineas will come home? Have kept them in for a month, let them out for 2 days, watching them, them seemed to be getting better about relaxing and foraging, grazing on grass, and becoming more acquainted with the yard. We let them choose about going back into their caged yard. All seemed good, then yesterday in the afternoon, we let them out again, and they just bee lined it into the woods. I am heart broken, I really was becoming quite fond of these guys. Is it really difficult to have adult birds?
