Our squirrels pounce on the feed bowl as soon as the chickens wonder off, so, of course, the bowl is empty when they come back. I think that it must be doubling my feed expense. They chewed through a rubber-made box I was storing feed in. They seem to becoming more and more bold, and I worry about possible aggressiveness, but, I can't seem to bring myself to killing any.
Put out less feed, and store it in metal barrels. Once the feed supply is gone, the squirrels will be too. Unless one were to contract rabies or something, which is incredibly rare, I very much doubt you will have to worry about any aggressive behaviors.
