Good job on this. Funny how you can see in the picture where you have just moved the coop. The cleaned away spot, where the coop just had been, is clear to see.
Great idea of having the run as movable as the tractor. Can't tell how/if the chickens get from the run to underneath the coop. Be good to have pictures as you went along building this because I'll bet someone will want to make their own.
This seems easy to build and if one wants to pay for instructions, then the link is provided. As far as a helpful article outlining plans, how to pictures, dimensions and drawing of a coop build, this isn't it.
