I just thought I'd share my two coops I use one is built from an old steel shed I got from my boss for the low cost of free. I repainted it and added the run I bought from TSC on clearance. It houses 16 chickens currently. The other one we just moved and started remodelling today. It was a seed starting green house I built two years ago that I no longer needed. It is 8'x10'. With an 8' peak. There is a gap between the two coops and it will be filled with a room to store feed, straw and other materials. The run for the new coop will run off the tall side. So the two setups will mirror each other. I plan to put gutters on and collect rain water to use on my field crops and keep the runs dry.
