We have our coop and run ready for the chicks and we have a 1 and 1/2 foot deep barrier around the bottom of the run/coop. My concern though is about a hawk that hangs around. Our neighbors have many different types of animals and some of them protect their chickens from predators, but I don't have that kind of protection at my house. I did find a type of netting that can be used to protect from hawks. It looked promising but I don't know how to put it up yet (have to ask a handyman if he can do it). Does anyone have a successful way of protecting against hawks? Thanks!
