Find a heavy rock to put inside to keep them from tipping it over.Okay that is what I thought. And I just remembered that one of the girls at TS told me that ALL of their first ducks (the ones we got ours from) had "gone swimming the first day there at TS" and several drowned.So maybe that is an issue for them.
I am making a waterer for them. It's not very tall, so I hope it works. It is a salad container that I bought salad in. I cut two squares in the top. Hopefully it will work till we find something taller.
