Hi all, I'm new here. We are picking up our 4x8 coop tomorrow and trying to determine the best location for it. The most convenient, level ground (we live in the woods on a hill) for the coop and run is on our old, unused leach field. The new septic system was put in last year on the opposite side of the house. The ground does not get soggy and grows grass. I'm not concerned about damage to the septic since it is obsolete, but rather the health of the chickens and humans who eat the eggs. I've tried to research how long it takes to restore the earth in an old leach field but haven't had much luck. Any opinions from the experts here? Thanks!
