Tonight I put my 6 month old BBW turkey hen in the hen house. Long story short, the pen she was in was that electric poultry netting - there were chickens in with her - and I saw coyote tracks on the outside of the fence. I decided I needed to move them, electric fencing doesn't work as well after the ground freezes. Anyhow, moved them all into the hen house, and the last I saw before I came in was my 6 month old BBW turkey hen standing on top of a nest box, about 4' high. The nest box has a slanted top (about 45 degrees) but that didn't phase her at all. It'll be interesting to see how long she can continue to roost.
