I have seen lots of threads on BYC of Hoop Coops/Hoop Houses made out of 2x4's, cattle fencing, and wiring. All of the ones I have seen are actual coops, and they are quite small. I was wondering if it's possible to make a chicken tractor for 23 chickens with the hoop coop style, but without the coop. I need an easy to move chicken tractor for my 23 chickens because I am having a terrible hawk problem and my chickens need to be able to get outside. How big would it have to be to hold 23 chickens comfortably? I know it will have to be pretty big, but would it still be moveable at the size that I would need it? My chickens wouldn't be sleeping in it, they would just be out in it during the day.
