I have enclosed a picture of my current Coop. Right now I can hold about 60 chickens in there and only have their roosts in it. I would like to keep as much space in there as I can. I had a thought that I would like opinions on. Yes, I am going to cheap and functional. I am considering 5 Gallon Buckets as nesting boxes, using 1/2 lids for the front little piece. My thoughts were to cut holes large enough in the side of my shed to fit the 5 Gallon buckets into, up to the large ring so it kinda seals. Sliding the buckets through the holes then building a 2x2 tic-tac-toe type frame on the outside to hold the ends of the buckets from falling down. Then build some sort of perch that they can use to fly up to the front of the buckets. How many birds per nesting box?
