We use lead posioning for raccoons and rabbits. It thins down their numbers if Dan is on target. I had a problem with wild chickens digging up my seedlings when we first moved out to the farm, but eventually, they all went to that great chicken farm in the sky. I wasn't sorry to see the rooster be the first to go. 3:30 - 4:00 am that thing would go off. We have deer, but if I can interrupt their trails early enough in the season I have less problems with them. Plantskydd, Deer Fortress and Electric Deer Fence tends to discourage them quite a bit. I try to collect the fallen apples from our trees and haul them down to the far end of the west pasture and it keeps temptation under control.
