Has anyone tried this? I tried to do a search but couldn't find anything. I've been looking at the Horseman's Pride Slow Feeder Lid thinking it might work as a waterer for my ducks and geese. The ducks would still be able to get their heads in the water but wouldn't be able to get their bodies in it. I think the water that comes off their beak would hit the lip and roll back into the bucket. Any thoughts?
