How does one keep the squirrels from eating the chicken feed while they're out free ranging? This has been going on for a couple months and I hate taking up their feed for all day. There's nothing else out there for them to eat during the day. While the weather was nice, I'd go out and sit while they ate the feed during the middle of the day and then I'd take it back in. BUT I'm not going to sit out there in this miserable weather. Any suggestions?
