I live in Michigan and we get very cold temps and snow for much of the winter. I raised my first turkeys ever this year that I hatched from eggs. Fell in love with the rascals and want to keep a couple of them (White Midgets) but they are getting harder and harder to go into their shed at night preferring to roost in the trees at night. That's fine for now but what about when we have sub zero temps and blizzard conditions? Thank you for any advise.
