Apologies if this has been answered a hundred times; I couldn't find it in a Search. I am placing a small coop with a small run for 5 hens in the next month. We have a well for our water to the house. The well is about 250 feet deep. With only 5 hens and a deep well, are there guidelines about how far away the coop should be from the well? At present, I'd like to locate the coop about 25 feet from the well access (lid). My hunch is I don't have to worry, but is there common wisdom about this?
