Ducks need to be able to dunk their heads. Mostly their nostrils to clear them. With the three Pekins ducklings, we are using a dog bowl. deep enough for them to get their beaks in good and clean thins out. They tend to climb in for swims. We do give them a twice daily swim in the tub. One if during cleaning time, when we clean out their bin. DH or I cleans the bins while the other watches the ducklings in the tub. The other is right before bed. The ducklings go to sleep and we get to sleep, too.
my girls just turned 1 in march. I'm not ready to lose one yet!!
