I have 6 hens and a rooster. My hens should be getting close to laying and I have bought some nest boxes. I am at a loss as to where to put them. Here's my setup: Inside of our barn I have a custom built coop with a roost that I close my chickens in each night at dusk. Every morning I open the coop & let them run loose all day, every day. I had originally thought that I would put the nest boxes in the coop area, but now I am thinking that the chickens will just mess in the nest boxes from where they roost if I try to put it in there. Is there any reason that I cannot mount my nest boxes in the barn a couple of feet off of the ground since I turn them out anyways?
