Very nice sketch...is it to scale? I see no dimensions.
Agrees on taller run, but I'm old and don't like to crawl thru chicken poop....or crawl anywhere for that matter....lol.
Let's say 4' x 8' x 8' coop and 8' x 8' x 8' run and all new materials with 1/2" hardware cloth (maximum predator protection)....$500-$1000.
Rain barrel to nipple waterers will need some fine screening/filtration or the nipple will clog.
