right now i have about a 3 foot kiddie pool for my duck and goose. Its small so it gets filled with poop each day and needs to be dumped out at night. having to refill it each day seems to waste a lot of water and our water bill has gone up thanks to the pool. I really want to get one of the giant sizes of kiddie pools that are at least 6 feet in diameter like this one http://www.brandsonsale.com/itx-58461.html?utm_medium=cse&utm_source=google so with one duck and a goose how often would i need to refill something like that? right now i have a small ramp leading in and out of my pool and the birds have refused to use it. i was wondering if other peoples ducks and geese will use a ramp up to the pool?
