We are building our first coop and enclosed run for 5 chickens, thats if one of them isn‘t a rooster. We have a 4x4 coop with it open underneath so that‘s 4 feet of run. Then we are trying to figure out if a 4-5 foot covered run would be enough For the 5 chickens? I would love any advice. Here is a picture of our coop in the works. Also, any advice on ground in the run? We currently have cleared dirt that has little roots and worms throughout. Should I cover with clean soil and sand? What about adding in food grade diatomaceous earth ? We have cream leghorns, Silver laced Wyandotte’s, and Asian. Thank you!
