Hi! I'm considering getting a dogloo for my girls so they have a much smaller area to huddle in during the cold, windy days. I searched the forums briefly, but didn't really see anything about whether or not it's hard to get them used to such a thing. I don't want to spend a bunch of money on something they won't use! Does anybody have any experience with getting their grown chickens to accept a dogloo and/or tips or ideas for how to do it? Thanks!
