I live 40 acres and want to convert one stall in my older barn for chickens. 10' X12' stall wood up to 4 feet, rails up another 4' and open at the top to rafters. I have electric and water in the barn.I want to raise hens for eggs for myself and maybe sell a few surplus. I live in Michigan. So I was thinking about starting with 10 chickens, but I wasn't sure about the 25 minimum from some breeders. Currently I have 6 horses that I care for in the other barn. I plan on putting wire mesh around the base and I have rubber horse mats that will constitute the floor. I was planning on putting netting over the top of the stall to keep other birds and prey out.
