Our run is bigger then what we need, but the grass is all gone. I'd like dh to install a door on the run, so they can go out and eat more bugs and grass/weeds. If I sit outside watching my girls free range, will hawks still fly down and eat them? I'm planning on keeping my Aussie by my side in case a dog or other animal come near my girls. She protects our house and yard anyways. Are the chickens more safe with me supervising? Thanks.
