Well this morning I went and checked on my layer coop and run. All chicken are accounted and safe. They go into the coop at night and the hatch is locked down tight. Only things that can get inside it are flat bugs. The attached enclosed run is also secure, I thought. Never had problems until last night. It is covered in 1/2 inch hardware cloth, secured in place with fender washers and #8 1-1/4" wood screw every 16 inch or so. Top of the run is also secure with same thing and it also has corrugated clear plastic roof. Only thing that can rip it apart is potential cougar or a bear. Other wise its secure. The base has a concrete apron all around so no diggers can dig its way in from underneath. Well some varmint (looks like a size of a weasel hole) has managed to tunnel from the raised bed, under a river rock walkway, under the concrete apron and into the run. That varmint must have been digging all night long. Sometime between midnight and 7:00AM when I go out to check. I'm going to fill the tunnel with extra 2"- 3" river rock and for safety measure bury more river rocks along the inside edge of the run and add hardware cloth backing to a depth of about 16 inches on the side that was attacked. Just what I need more friggin work!! Meaties coop has yet to be cleaned out and covered in tarp for the winter. sheesh.
