I am a new owner. North east Mississippi, own 16 acres have 8 new chickens about 5 months old. A rhode island red rooster and hen, a americuna roster and 3 hens and 2 mixed hens.I have read some books and watched a lot of videos to prepare but most said they only clean the coops once every couple of weeks or a month. I built a chicken tractor with nesting boxes and the boxes are filled with poop every morning. Is it ok for them to sit in that much poop?
