I am a new chicken owner; I have 3 Rhode Island Reds and 3 Leghorns--all 4 weeks old. I just built an 8x8 run with a roof (will be building a coop to go inside the run) and now, of course, I'm having mega anxiety that I've missed something or underestimated the power of a predator. I used 1/2" hardware cloth for all of the sides and I also wrapped the top with hardware cloth before putting the roof on. I attached the hardware cloth to the frame with staples using a staple gun--will this hold or should I retro-fit with screws/washers? I have bags full of the screws for metal roofing that would work, but I didn't think to use them. I did not bury the hardware cloth--theoretically this is a movable run--but I did cover the "floor" with chicken wire. Is this enough? We have all kinds of predators where I live, so I'm trying to anticipate anything that could happen and protect my girls! Barnrat 4 dogs, 6 cats, 7 horses, 6 chickens!
