If your fence does not have a top rail or anything the turkeys can perch on, it may contain them. If it has a top rail or something they can perch on, they will jump up there and invariably get down on the wrong side of the fence.Can I ask you one more question? We have 5 acres with a 4' no climb fence around it. The turkeys are heritage breeds and currently kept in a 10x16 hoop house. If I was to let them out of the hoop house, do you think they will take off? The one that has been loose has stayed in the area for the last several nights and is starting to hang with our chickens. I know they can fly not like broad breasted but not sure if they will stay or go, and I do not want them to fly away! Thanks
