I am building an over under, closed in coop/nesting area on top, chicken wire/wood run area below. Is the over/under a good idea? how about with coop on bottom, run on top? I am insulating the coop in real good. and will put plastic over the chicken wired outer area for during the winter months. I am going to be putting some Christmas lights on it to provide light to get eggs during the winter months. Do I only need lights on the outside run area or do I want some inside the coop as well?? Will the pine shaving I use for my chickens work in the nesting area? Do I need to put some sort of nesting box like I provide for my chickens? When I get to the animal feed store, what should I ask for to feed some coturnix? I have plenty of laying feed and cracked corn for my chickens, vege scraps, eggs, etc.
