The guy I got some fencing from had some nestboxes that were roll away, but they were wire. He says if youleave the door open, they can get in and out. It was kind of dark though and I didnt get a good look at them. Does anyone have a pic of something like that? i'm trying to figure out if I can use them in my set up. There were ten 1 ft square areas, and he only wants $15, so if they work, itseems like it'd be a good deal.
