Hey, all! I'm a huge researcher, but I'm at a loss. I'm trying to design a portable coop and run to be used on uneven terrain. I had what I thought was a great predator proof run design, but with my uneven/sloping yard, I'm afraid a critter or snake will get underneath an edge of a solid run if it's not completely flush with the ground. I've read where folks have used electric netting and moved the whole fence. I really want to be able to move my future chickens to fresh pasture, but I want them to be super safe from snakes and overhead predators. My coop is the Formex Snap-lock large coop. Trying to get a plan for attaching an automatic door to it, too, but first things first. Any one have any ideas on an easily movable run that I can attach to my coop that will provide protection on uneven terrain? Thank you!!!
