We just came into possession of the body of an old cow trailer and we're converting it to a chicken coop. It is a steel tube frame, with the tubes spaced not more than 8" apart horizontally. It has framing for a wooden roof on top. The structure is 6' tall, 16' long and 8' wide. Before now, we've lost chickens to weasels and dogs, and we are determined to make this one as secure as possible against predators. Our plan so far is to wrap the bottom 4 feet with hardware cloth, burying the bottom 6" of that in the ground, with the remaining height and roof covered with regular chicken wire. Will this be sufficient to protect them from racoons, weasels, or any other predator? We plan to build a sheltered nesting area inside the structure at the end opposite the door. How does this sound? Any suggestions? Thanks so much for your input and advice!
