We are getting ducks and geese later this spring, and although they will have access to drinking water, I do not have a pool in the coop/run they will be sharing with the chickens. We usually let the chickens out every afternoon when I get home from work to free range for a few hours before dark. I can have a swimming pool for the ducks outside the coop/run for them to swim in at that time. But is that long enough? And if they do not get let out for a couple days straight, and only have access to drinking water, will that be a problem?
