Oddly, my Seabrights stay in the yard as do my D'Uccles. But the Old English are real wanderers. All are Bantys. My four foot fence all around my property is no deterrent. If they feel like it they will fly up to my house roof...two stories. I don't want to clip wings either. Fortunately I live in a very rural, heavily wooded area without many neighbors. They sometimes do it in stages like flying to the top of the covered runs, or to a fence post first...but sometimes I let them out and they will fly all the way from the coop door in a straight line over the fence, and into the woods...about 80 feet. It is not uncommon for them to be flying ten feet up in the air.
