What do you use to protect your run? We have a run attached to the coop and our door is a flap as during the we are gone early to work and come home after the girls' bedtime. The flap allows them to go freely into the run. We want to possibly expand the run, but do we have to use hard wire cloth(more expensive)? Can I use chicken wire(cheaper and we could make a bigger run)? No predator incidents so far but the girls are only 2 months. Our biggest concern would be hawks but we also have coons, opossums, and foxes in the area.
