Hi
@we3ernes
I agree with the need to be able to stand up in both coop and run. Those are both important over the long haul.
We have a simple 3 sided coop with a doggie door for the chickens and human sized door for us. It would be very easy to expand, take off one wall and add more length. We can add or remove wood panels to the front as weather dictates, right over the 1/2" hardware cloth, attached with screen mounts so 1 person can do the job.
We decided on deep litter in the coop before we built so we put down concrete blocks first, then built on top of those to keep the wood from composting too. Plus, termites won't be an issue. I also have nothing on the floor of the coop other than litter and a feed bowl. Keeps it clear for stirring litter and if we have walk in the coop at night.
A poop board is an addition we made. It's easy cleanup a couple times a week and I put the poop in our composter. This helps with flies in my experience.
We hung plastic nest boxes on the walls. Keeps things off the floor, super easy to clean if an egg gets broken...sometimes there's discussion over who gets to use the favorite box and more than one girl gets in it
For storage we have a couple nails on the wall for a kitty litter scoop and scraper as that's about all I need most of the time. And a five gallon bucket for poop collection is nearby. I use my regular rake, an outside broom and wheel barrow when I clean, no specific tools just for the coop.
For the run, shade, shade, and shade. Your climate is similar to mine...you can never have enough shade! Don't forget a place for mud puddles.
Good luck in your planning and build. Looking forward to pics!
