Halloween night, I lost my 8 silkies. My coop was inside an enclosed run made with 1/2 inch hardware cloth and treated lumber (4x4 and 2x4). Hardware cloth was chewed and torn opened, fencing nails still embedded, but hardware cloth torn away from them. Entire run was moved from foundation. We were so very sad to lose our birds but the destruction was shocking. No signs of digging. We are assuming it was several raccoons and are preparing to install electric fence. Any other ideas to prevent future loss??
