This nesting box is very well designed and built to last a lifetime. I was impressed by the heavy materials used, and the quality of the fit and finish on everything. When this thing was engineered, they paid attention to details, and designed it to be extremely practical and easy to use. I've tried a lot of different nesting boxes, and this one is way beyond any of them in quality and ease of use. They've designed something that can be used access eggs from the inside or outside of the coop, but also keeps the eggs clean and undamaged, prevents snakes and other critters from stealing eggs, and loos appealing to chickens to nest in. No more losing for eggs on the ground, or losing eggs to other hens or pests. When I build a new coop I plan on ordering a half dozen of these nesting boxes and building it to put these to use. I highly recommend this nesting box.
