I'm having a horrible problem with squirrels. There must be at 10 to 15 of them that come into the outer coop and eat the food. Sometimes I find an egg on the inside coops floor. When I open my door and bang the cans they all run. It's terrible! My chickens and guinea fowl seem to have no problem with them eating the food. How can I get rid of them? My outer coop is 10x12 feet and 10 feet high and it looks like this summer I'm going to have to cover the entire coop with hardware wire. My inside coop is safe but I leave the door open so they can lay their eggs. Help!
