This chicken tractors will last, they are easily pressure washed for keeping clean. These are made with quality materials, mechanical lift system. They are protected from predators . We added homemade runs so they can safely go outside.  The panels keep the wind and cold in the winter. We wired ours with a light which keeps warmth in as well as power for water to keep warm.

The Chalet is our favorite design, the extra height in the roof works better for roosting, cleaning etc.
