In some Buddhist temples, you pay a little bit to buy a bird in a cage, and then have the joy of releasing it. Yesterday we took our 20 Khaki Campbell ducks -- ducks that have lived in a stable, and have spent every day in a grassy field -- and we released them onto our 1/4 acre pond. First time they'd been on water, other than in small pools. Yes, the fox may get some of them. But I think this is a choice they'd make if they could.
