We are in the process of building a new coop at our new location. My husband went to our take the windows off my old coop and noticed something had pulled off the hardware cloth on the corner of the run. It was attached with heavy staples the only thing I can think that might have been strong enough to do that damage was a coon. I am glad the little critter didn't get any thing because the coop and run are empty I rehomed my flock over a year ago. I have almost 4 week old chicks and I will be reinforcing the run with U nails! I have been through 2 massacres in the past and I never want to go through it again, I thought I had been over predator proofing I guess I was wrong. Time to bump it up a notch!
