Hello BYC community! I read a lot of different articles/posts about the deep litter method and I'm interested in doing that for my chicken coop. However, even after reading a lot of posts, I am still a little confused so here are some questions I'm hoping can be answered: (1) Some people say to sprinkle some food grade diatomaceous earth in the mix to help reduce odor and natural pest control. However, I also see some posts that discourage the use of diatomaceous earth because it kills the healthy composting microbes. So which is actually better - do I use it or not? (2) Do you use the deep litter method inside the chicken coop itself, inside the run, or both? I purchased a coop online that contains both the coop to house the chickens inside and a run, so I'm wondering where I'm supposed to do the DLM. (3) Some people suggest using "sweet pdz horse stall refresher" to help with odor. Can I use this in conjunction with the deep litter method? Or will it be unnecessary? Thank you!
