I was so excited when I received these for my chickies. It was very easy to teach them to use it. I was less excited when I went to clean them for the first time, and realized to do so I would have to unscrew them from the wall. They don鈥檛 simply come off. I wish it was some sort of hook system instead. I don鈥檛 know how long I鈥檒l be able to keep it in the same spot and reuse the original screw holes, and I don鈥檛 want holes throughout the coop 馃憥馃徎馃憥馃徎
