Tractor Inspired by Drawing Here!

This tractor was inspired by the one on your site in Google Sketchup.  It is home to 5 bantam hens (1 Leghorn, 2 Silver-Spangled Hamburg, 2 Polish).  We used skis as runners & to keep the wood off the wet ground (Seattle area), but will probably add wheels since it's heavier than we thought it would be.  We added a cross-piece 3' from the end of the run so we could have a hinged lid & hang feeders if needed (we currently have feed & water on the sides so we can refill with out opening the run).  All but the the hardware cloth & a couple of 2" x 2" for the frame were recycled or free materials.
