We are new to this chicken keeping obsession, and want to do it right. We have a 10x12 garden shed we were hoping to re-use as a coop with some modifications, but it sits approximately 20 feet from the well head. Is this too close to our water if we put the run on the opposite side away from the well? We will have 12-15 chickens at the most, and the shed has a floor, so there would be minimal waste seeping into the ground that way. The chickens will be free to roam during the day, both in and out of the run. Any help, advice or links to share?
