I am considering getting some pigeons. Once I have them properly set up in the loft of my chicken coop and they are out flying and doing pigeon things; what are the chances that they will stay in the barn with the wild ones that live there and not return? Also the opposite; will the wild ones come into the pigeon loft with the tame ones? I do not know yet what variety I will keep, if that makes a difference. Thanks--Terri O in WI
