I need to do something about the smells in my chicken runs. Despite the fact that I clean coops everyday, and dry rake the runs, the endless rains here are making the runs smelly. I read that hydrated lime is bad for chickens; hence do not get products that have calcium hydroxide in it. My first question is; the garden lime I purchased has calcium oxide in it. Everything from chemistry class tells me it is okay because it doesn't have to "hydro" in the lime; however, I need to check with the experts on this site. My plan is to rake all of the pine needles out of the runs and then sprinkle some lime and then put new pine needles down. My second question is; do you think the barrier of the pine needle is enough, or should I add more dirt and then pine needles? Thank you for helping me with your experience.
