Ok, I keep thinking it is not good to let the coop get that much poop and feed in the shavings... I am cleaning it out and changing shavings every week or two. At what point do you know you need to clean.. I keep reading about diseases caused by not clean coops etc so now am paranoid about it. My coop has a slightly raised wood floor covered with vinyl. Do you spot clean water spills ?I have a tile floor in my coop and after a good cleaning I initially put down about 4-6 inches of shavings sprinkled with a little DE to help keep it dry. Then as the shavings breakdown or when it seems to need freshened up I put in another two or so inches of shavings. Then every three to five months, depending on the season I totally clean the shavings out and start over again.
