I bought 5 of them to add to my already 10 nesting boxes and they are a huge hit. Preferred over the other boxes by the hens. They were easy to install and a breeze to clean when an occasional accident happens and an occasional egg gets broken. I will be switching over all my nesting boxes to thieve the next time they go on special. Oh and I forgot to mention. With these boxes the hens CANT sit on top of them because of the design. Wonderful
