Better just have them stay in there if you don’t want to chase them in during bad weather then..they’ll be fine :).
Two of my geese when I came out to feed them after they’ve been inside all day :D:
How big are their sleeping quarters? When I have weather like that mine just have to stay put. I come out once a day to feed them and lay down a fresh cover of straw. They recently had to spend four days in their coop and they did fine, they were just really mad.
