My current coop, rabbit hutch-like is 5x3. In a few months I will be doing a large McMurray order, and would like to use this for a bantam coop. I was thinking I could hold about 8, with the 15x5 run and free ranged. I'll probably also divide the nest boxes in half. Very excited! I have only had one bantam before, Clover, a few years ago.
