Hi! The chicks will be moving outside tomorrow. I will be switching to a metal 2 gallon double wall water font which I intend to hang a few inches from the ground. We're in Louisiana and have serioius mosquito problems. Does anyone know if it's o.k. to use those B.T. donut shaped dunks in the chicken water? We use them in our miniponds and container bogs and they work great to prevent mosquitoes. Just wanted to be sure. Thanks!
