My husband had built this shed to look like an outhouse out of rough cut lumber about 15 years ago. When we decided to get chickens he built the nesting boxing, added a roost above, and cut a small door for the run. We re-purposed some metal shipping frames to make the run. All in all, using things we had around the house or left over materials from my husband's place of employment, we only spent about $50. On supplies, mainly the chicken wire.
