I use those with my chickens. They have been using them for 2 years. I’m going to try it with the quail tomorrow when the order is delivered. I got 15. I needed more for future ideas. I’m thinking about doing the pvc pipe waterer for my quail pens. I’m going all out for these dang quailI bought the cup waterers that work via a float valve. Those should work for quail. IME they're too easily broken to use with anything bigger.

I absolutely love my quail. They’re the sweetest things.
