Bought a cheap box of precut, self-adhesive vinyl tiles from Lowe's to use for the nesting boxes. They fit perfectly! All in all, for a coop that is 8'x12' with 8 nesting boxes, we spent less than $32 on floor covering. I'm going to box off their roost area and put down the Agrisand stuff that can be sifted with a cat litter scoop daily, and equine absorbent bedding throughout the rest of the coop. All I'll have to do is sift poo from the sand enclosure every other day, and sweep out the rest of the coop every 1-2 months to keep it looking great.
