I was given 4 milk crates to use as nest boxes. I have seen many different ways to set them up on here but was wondering what the consensus here was.... Mount them on the side and put a lip on the front to keep the material inside OR Mount them with opening up and then cut a "notch" in the side so that they can climb in and use it. Mounting them with the opening up would seem to give more "floor" area for the chix to lay on but maybe thats just an illusion when looking at them? Any and all suggestions appreciated! Feel free to post any pictures if you have them.
