Can I make my horse trough into a bather for the ducks?

[Miss Lydia]

I just put a 10 foot by 3 foot by 2 foot deep trough into the ground for my 4 2 year old ducks. They've only had large dog pools until now. Well this morning I found my female Pekin dead inside...she unfortunately drowned. I thought to myself all day yesterday about that...I hope if they get in, they can get back out...nope

So sorry for your loss.
