It's my first time with chickens so I still need tips on the best coop and run designs. Right now I have a 4 x 2 coop with two 1 x 1 nestboxes attached to the side that is raised a foot above the ground. It has a pull-out wooden "tray" filled with pine shaving on the bottom and pull-out nestboxes so I can clean the pine shavings out. There is an opening in the back of the coop and a ramp going out into a 6 x 6 run area. I actually used to use the coop for quail a few years ago so I just took out all the wire sides and floor and replaced it with wood. I was wondering if there is a more sanitary, easy-to-clean design for a chicken coop and run because the smell is sort of trapped in the coop. Even though the coop has a bunch of little cracks inbetween pieces of wood and the opening, the air doesn't really circulate. My local hatchery just keeps the chickens in a fenced run with a tin roof and nestboxes and covers it with plastic when it gets cold. They dont have a little shelter in there or anything. I was thinking about doing this becuase they get more fresh air and sunlight plus you don't get that blast of chicken smell that I get when I open the coop doors. It hardly smells at all. I was also wondering how many chickens I could fit in the run I have (36 sq. feet) if I move to my hatcheries design.
