Hey everyone, I am having a problem with ground squirrels coming into enclosed chicken yard. They come in to get food an water, as both are in plentiful supply. The yard (12'x12' ) is wrapped in chain link, and I have 1"x1" wire on top of that up about 4ft from the ground. It has been a really hot summer, and I think that is what is going on. I didn't have this problem last year. Do I need to worry about disease from the squirrels? We live at 4300Ft. elevation and our property adjoins Cleveland National Forest in San Diego CO. Any advice?
