Well done on the building of this. I think the run is a little small for four birds. Have you lengthened it?
I like the idea of having the roof line continue from the top of the coop on out to become the top rail of the run.
I like the idea of not having to lift the weight up when you move it, but do you just secure the hens inside the hutch when you wheel around?
Good job for two novices! I'm not getting a clear idea of how the coop itself is set up. The pictures don't really explain that.
Good job on building this coop into the run to make both of them better. Be nice to have some more details of the coop build itself.
