Everything. I've seen chickens take apart chicken wire. If they can get trough it, you can be sure just about any other threat can. Get yourself something heavier duty, like hardware cloth or chainlink.Oh I never realized that. What doesn't chicken wire protect them from? We knew to bury the wire to prevent tunneling, but the only things I thought we had to worry about in our area was fox, raccoon, and hawks.
So just read up a little more and I think I see what you mean. Chicken wire isn't strong enough to keep a determined predator out, even if it's completely enclosed. Thank you for giving that heads up! I appreciate it. You can tell it's our first coop lol
