I recently purchased this chicken tractor and really like it so far. Do I need to do anything to improve it to keep predators out? We have coyotes, skunks, and raccoons for sure. The wire is 1/2” hardware cloth. The run on the bottom and access door on the coop top each have one 2-step latch. The ground is open. I’ve wrapped bungee cords around the nesting boxes to keep them from being lifted open. I’m considering adding a hardware cloth apron. Thoughts?
