I saw your post and I am so sorry for your loss.
I have something that might work to leave water for them to drink that they cant play and splash out all the time but might stand up to them longer. I know it has worked so far with my new ducklings. Then you could still do pans to let them dunk their heads in through out the day. Maybe if they had access to water for drinking more through out the day that they didn't play and spill all over it might help. I have to say after I figured out the trick to these i like them.

Not a perfect solution but an idea to try.
