My ducks kept getting eaten by bobcats, and I didn't want to keep them in their house all day when I was away. So, I made a "duck tractor" for the times we're away from the house!
Local homesteader was getting rid of the trampoline frame, so we picked it up. I assembled it, wrapped chickenwire around it and on top (securing with wire from the roll of chickenwire). It works well! I drag it to a new spot each day. It takes all of maybe 2 minutes to drag it. It takes longer to refill their waters and bring their food out, than it does to move it. This allows them safety, fresh grass and bugs, and clean place to be. The 17 ducks and 2 geese make a lot of poo in one day!
I have crazy amounts of video of me assembling the thing, as my son had possession of the cellphone. No pictures of putting the wire on, as he didn't have the cellphone at the time. That was, by far, the most time consuming part, though!
