I have read a lot about using deep litter method in the coop and I'm not sure if coop includes run? We have a new coop/run which is on dirt. After they have torn up the dirt I figured we would put some pine bark down. Should I keep deep litter in the run and coop? Our run is fairly small at the moment but we are in the process of creating an expansion. Wondering if I need to put several inches of pine bark down in the entire run and then just keep adding to it and stirring it up. Do I do the same in the coop? Or do I keep the coop fairly clean and toss the litter into the run? Thanks for the input!
