Good question - Our birds sleep inside, under, or around their mobile home. In a temperate climate, they're pretty easy to please!
WoodstockSanctuary - we obtained many of our hens from other farms after they were 'spent,' so in a sense we rescued them much like you do. So, they had been de-beaked long before we got them. They do, in fact, forage pretty well in spite of that. However our newer flocks, which we obtain as pullets, are not de-beaked.
