Nice set up with only one concern and that is the largely spaced fencing on the run especially at the bottom. If you are not locking your hens in every night a coon could easily reach through and grab "parts" of your chickens! You might want to put 1/2 inch hardware cloth around the bottom part of the run. LOVE the rubbermaid tote nest boxes!! Awesome idea!
The chickens go in every night so we arent worried, our neighborhood has many dogs and we needed strong fencing around the bottom area that hopefully would deter them if they got into our yard, but first they would have to get past our dog.
