We have a major deer problem in the neighborhood. I've seen herds up to 2 dozen deer in our backyard browsing on our landscape plants and poopig & peeing. It didn't used to be this way until the next-door neighbor started to feed the deer in the warm weather months causing them to congregate in our yard. She stops at the first freeze and lets the deer fend for themselves over Winter. They still congregate in our and other neighbors' yards.
