farrier, i'm kinda challenged when it comes to posting pics but on those 5 gal. bucket nests, you must have lids. if you know someone who does sheetrock for a living they usually get a hold of quite a few. i cut a hole in the lid leaving the ring intact and a bit more at the bottom to keep straw in the nestbox. i built a framework facing the wall and put a screw or two through the bottom of the bucket into a board. you will need the front end of the bucket resting on a board/landing to keep the screws from tearing out of the bottom. on the bottom side of the bucket i cut another hole for me to collect eggs. i hung a dark cloth over the egg collecting hole to keep hens from entering and to keep it dark. so the hens go in one hole and i collect eggs from the other.
