I'm almost done with my coop (will try to get some photos uploaded before the girls go out). I've created 3 nesting boxes from 3 dresser drawers that I purchased from The ReStore for $.50 each. The drawers are about 12" wide by 16"deep and have walls that are about 5" tall. They are secured to a shelf that sits about 12" from the floor of the coop and have another shelf about 15" above them to keep it cozy. There is a nice roost about 5 inches in front of the boxes that they could hop up onto before entering the nesting boxes. My question is whether I need to build dividers that separate the three boxes from each other or whether the 5" wall of the drawer is enough separation. OK, I guess I have two other nesting box questions. Can I fill them with the same pine shavings that I'm using for the rest of the coop? And should I allow my 6 week old pullets access to them right away or block them off until they are closer to laying age?
