I only have BAs and EEs but re: nest boxes, I use Rubbermaid (or similar) totes without the lid. I cut a "U"-shaped entrance in one of the short ends. Easy to clean--just scrub, rinse and dry. Can be moved to different locations if necessary. A variety of sizes available to fit the coop and the hens. No parasite critters setting up shop in hard-to-clean crevices, no rotting wood, etc. And having had horses, I've always used coastal hay as the nest material.
