Turkeys, once they get reasonably started, are tough as nails. My nearly 6 month old jakes roost on a fence whose panels have 1.5” aluminum top rails. (This is temporary because winter rudely showed up several months early.) They insist on sitting up there in all weather though I put a tarped tractor in the yard for evil weather. I was putting their food in there to keep it out of the snow, but they didn’t like going in there to eat it. The funnies strut around in the yard all day (all but two or sometimes three of them who fly out) when they could be running around outside with the jennies and the chickens. I would put them out, but I really don’t want them in the (open) chicken yard, picking on my girls and eating their food. If we ever get a warm day (after we get the poly on the greenhouse) it will be time to decide who goes to freezer camp and who inherits the chicken coop.
The weather here has been horrible ever since October peeked around the door. No ice storms but lots of wind, snow, sub-freezing and even a few sub-zero nights, none of which fazes them a whit. The jennies sometimes spend the night with their girlfriends in the chicken coop, but more often choose to roost on its roof. Other times they sleep over with the laddies on the fence.
My (mostly) Sweetgrass poults usually choose to sleep in their grow-out coop with the not-currently-chosen roosters. There’s a sawhorse in their yard that the bolder amongst them sometimes roost on if there’s a warmer night. They’re around three months old and already stunning. (Thanks, R2!)
Anyway, I’m getting off track. Turkeys are unbelievably tough. They’re North American natives and not much changed as far as I can tell, besides all our “modern” pretty colors. We have wildlings wandering around too, and they’re also gorgeous. They survive magnificently with absolutely no help from me.
Put their water in their run/coop. Bring their food out in the evening twilight and they’ll learn to follow you into their yard. Bring them treats once in a while and they’ll mob you as soon as they see you. It’s so funny! Make sure the yard fence has no top rail or perchable posts... floppy is good as long as it’s secure. You might consider making their shelter with a steep shed-style metal roof. I would trim the top edge of the roof with some floppy wire fencing to keep them from roosting there and eventually flying out. That way, they’ll (mostly) only free range when you want them to. Have fun. Turkeys are the best.
