About 2 years ago (wow, time goes fast) I put up a thread about how I was going to use an old dog pen to build a coop/yard with. https://www.backyardchickens.com/t/574140/my-new-project-elevated-coop-from-dog-pen We kind of shelved the idea as cost was an issue and committment to the chickens, but my wife is hardcore set on getting fresh eggs, so here we go again. *I will supply pictures as we go, but just brainstorming ideas right now* Our neighbors moved away (ok, abandonded their house), and before they walked away, they told us we could take the homemade jungle gym they were leaving behind. Again, 2 years later, it was knocked over by some kids in the neighborhood and left to sit in the weeds. Well yesterday I went with my braun and sheer luck and literally rolled an 8 foot high pressure treated jungle gym over a 3 foot fence and into my backyard incurring a little damage but nothing major. So now I have a good amount of pressure treated lumber including a 4x4 platform made like a deck. I plan to skin the whole thing in plywood, but it will fit perfectly in my dog pen with only cuts made to the 8 foot 4x4s(?) My first question is this one: Can I run hardware cloth under the whole bottom of the pen as to deter anything digging into it from below? Will this bother the chickens to have hardware cloth on the ground (covered by something, haven't determined sand or hay. Will this bother them for scratching? It's only about 10 foot x 10 foot pen.
