We have a large fenced in area for our chicken run, and I need to figure out some way to cover it. We have hawks-My 7 week old chicks are currently out in a tractor, and twice a hawk has swooped down and landed right on top of it. The run is approximately 30ft by 50ft, so very large. I really don't know what I am going to do about this. Maybe I could just keep them in the tractor until they are full grown? Still-I am worried that a hawk will still grab a grown hen. Is it feasable for me to use the netting? If so, then where do I find it?
