Looks very nice! I congratulate you on how nice it looks and having used pretty much all recycled materials, you saved money and didn't consume yet more "stuff." I see that you used pallets to fashion a fence, good thinking! I tried to make my coop out of as much material that I already had on hand as well. You can see it if you want by clicking on "My Coop" on the left under my name.
Do you worry / have risk associated with predators (dogs, racoons, coyotes, fox, possum, whatever is common in your neck of the woods). I think I saw chicken wire around some of the coop enclosure and was wondering if you worry that it won't be strong enough. Most predators can tear through it VERY easily. It's really only good for keeping chickens in but not even a challenge for anything trying to get a tasty chicken dinner. Those of us with predator risk use hardware cloth. The 1/2 inch square seems to be best as the openings are too small for most predators to even stick their hands through. Only really small predators (like small weasels) are reported to be able to get through it.
I'm in an area with a very high predator risk factor and I free range (no fence, no run, secure coop at night) so I'm really cautious about predator proofing my coop. I used 1/2 inch hardware cloth, lined the outside of my coop with cinder blocks, buried a row of cinder blocks under the walls I built, and having double locks on the hardware cloth doors with spring locks that even a raccoon with his dexterous hand-like paws can't master. If you're interested, check it out at the "my coop" link.
Looks terrific! You have much to be proud of!
