I've read many posts on here as well as scoured pictures on chicken runs. I need a new one. I've had ours for a few years and with all of our torrential rains and flooding it's lost it's integrity. Many of the posts I read have the hardware cloth on the bottom and then other fencing above. Why is this? The farm fencing is not secure since weasels can fit right through it. We have had a weasel in our coop and I NEVER want one again. I love the idea of saving money using something other than hardware cloth...but is it safe? Do weasels only come at night when the chickens are inside the coop and safe? I think the weasel is the smallest predator that I need to worry about.
