This is the result of spending way too much time designing a chicken tractor. I wanted something light enough for my kids to drag to the next spot (or tow to the next spot with the lawn tractor), that looked presentable, and would work for a few hens.
The crank handle raises and lowers the ramp and locks into place.
I used spring latches to attach the ends. The hairpins were added for extra security against raccoons.
