Looks good. It's already been mentioned and will now be seconded that you need to run a lower row of 1/2" hardware cloth over the chicken wire to protect them better.This is my coop and run. My husband and I built it.
I would also add more organic material into the run for litter. I use a thick layer of wood chips that I get for free at a local Town Highway Department garage where they shred the branches that are collected curbside.
A few more things in the run for them to perch on or dig around would also be nice for them.
