Hello! The squirrels as our house have suddenly decided to start getting into the chickens run/coop. The chickens will attack when they see the squirrel and it runs around crazy not being able to find its way out. I tried to get it out but I have not been able to. How concerned should I be about the squirrels getting in? Will they bite and harm my girls? Or will the chickens get sick if they kill and eat the squirrel? We have never had this happen before so I am a bit lost....Thank you!
