This may be a stupid question. We are going away for a few weeks and while I do have a chicken sitter, I felt the need to add extra water options to make myself feel better. I bought a second 1 gallon traditional waterer with the plan to put it in the run but then realized that having the sitter trying to open the run door would create more concern (it's a tricky door). I decided to just zip tie a bowl to the side fencing. My only concern is are these chickens going to stick their heads in too far and drown? I'd say it's 3 inches deep.
