I originally wanted to build a movable tractor like the Chick-N-Barn but it is going to be too heavy so, I'm taking Patandchickens advice on making a summer tractor and thinking about a more permanent coop for winter. About the chicken tractor, I have left over cattle panels on hand the 16 ft. variety. I do use these for my llamas and make summer loafing shelters for them by making hoop houses and covering them with tarps. These would me too big for what I have in mind for three chickens so, what if I cut the cattle panels in two pieces and attached them to a 2x4 frame to make a detachable run. Of course, covering the whole thing with hardware cloth. Here are my questions 1. Would I also need something like field fencing to put over it because of predators? The cattle panels do have the big squares and I have heard a fox can cut through hardware cloth (mine is 20 gauge). I plan to cover part of it with a tarp for shade. I would also put a 2 ft skirt all the way around it and weight it down with cement landscape timbers that I have on hand for the digging varmints. The timbers could easily be rolled on and off each time I move the coop. 2. I could just make some sort of light weight box for the coop part and put it on wheels. Anyone got any ideas or pictures? I do want to move them around with the llamas for added protection.
