Howdy! I recently purchased a 1 gallon hanging waterer from TSC, the red and white kind with the twist on bottom. I've got it hanging in the coop and can not keep the birds from knocking in to it and draining it. I had the smaller stand version, not hanging, and they'd knock that one over and it didn't hold enough water. Anyone have any good ideas to keep the water where it belongs instead of all over the floor of the coop? Thanks!
