Over 20 years ago we built a beautiful chicken shed. I loved my chickens dearly. Many years later I moved and I’m now on a smaller lot. Like many, things are tough prices have risen, and I can’t afford to build a beautiful coop and don’t live where i used to live. so to get to the point I’m thinking about a resin shed 4’7”w x 3’D x 5’2”h. I want to make a hoop run 3’W x 4’H. Not sure of length yet. The area where I need to put it has a thick layer of small rocks I guess like Riverstone. I’ve read about Bumblefoot and I’m concerned for the chickens when I get them. Physically, I can’t remove them there’s too many, so I was wondering if I could put hardware cloth down on top and what do you recommend, 1/4” or 1/2”. I would line the bottom of the run with that as well as coming up about 12 inches on the sides all around, then encasing the rest of the hoop with wire fencing. What can I put on top of the bottom wire to protect their little feet? Is there outdoor inexpensive runners made of rubber? Thank you very much.
