Some of you remember the two new units I built, with help from my grandsons, last year. They have 12 holes or coops each for bantams. They are loosely based on the LF breeding coops I built a few years ago. These units are 6' high, 2' deep and just over 7' long to fit against the wall, between the posts in my post (pole) barn. The 1 by 2" welded wire gates slide up to allow for just enough room to reach in and collect eggs without giving a huge opening for flighty birds, like my Vorwerks, to fly out. I used 1/8" by 2 1/2" flat steel across the fronts to hang feed and water cups on. The lights are 2.5 watt "warm" LEDs. The flooring is 1/2" treated plywood. I have pullets in the top rows and cockerels in the bottom rows that visit the pullets a couple times each week. I use
PLASTIC EDGE PROTECTOR on the cut edges of the welded wire. I added roosts in each coop using 5" 2 by 4 studs.
