Our 3 peafowl (2 hens and a cock) have been in trees for 4 days and won't come back into their coop! I could only hear them beeping a few days ago; now I don't hear anything! They've been in the coop for about 2 months and I left the door open to let it air out and hoping the chickens would get over their illness. Then, the peafowl went outside and flew into the trees nearby, the next day they were further away and now I have no clue where they went. Do you think they're gone for good or is there a way to get them to come home?
