I lost 4 of my 8 chickens lastnight or early this morning and have a 5th one that is walking around but obviously injured, and I guess time will tell. I am both sad and angry right now! The predator (I'm guessing coyote) dug under fence to the chicken run. I've filled the hole and lined the perimeter of the fence with cinder blocks that I had sitting around. I know that the predator will be back so for starters I guess I'm looking for ideas on a more permenant solution. I've tried the electric fence but the grass grows up and grounds the wire so it's lot's of maintenance and daily testing. Secondly I've been considering moving my coope to give my girls freerange of my fenced fruit orchard although that gives me much more fence tor try to predator proof, I'm wondeing if the 1500 square feet of free range area would give them more room to get away in the event of intrusion or if I should just concentrate on fortifying their existing chicken run (about 100 square feet) I've always just left the coope door open for them to come and go as they please but will now be shutting them in at night but I've alsow seen coyotes on my property in broad daylight. Any suggestions are appreciated.
