During coop clean-outs, it has long been a tradition to sprinkle agricultural lime on a dirt floor in an effort to mask aromas, but this practice really has the opposite effect of what was intended.
Lime is alkaline, and an alkaline environment is ideal for the bacteria that create ammonia. Lime speeds up the release of ammonia by raising pH levels.
Chicken coop fresheners (Amazon) such as zeolite, herbs, and order control sprays are superior options for neutralizing ammonia and lowering litter moisture.
