So, I'm using the DLM in my coop. I rake every day and add new litter about once a month. The litter isn't wet or even damp. There is a lot of ventilation. I've been keeping both windows open and they're perpendicular to each other. I run a fan on days that temps are above 80. The past couple of days I've been detecting a slight ammonia odor. What do I need to add to get rid of this? Lime, DE, Stall-Dry, sweet pdz, or a combination of two or more? So far, I haven't used any of these products.
