How do you use Sweet PDZ in your hen house? Do you sprinkle it on the floor before adding the pine shavings? Do you mix it with the pine shavings? Have had a dry warm summer with no odor problems until this week when it rained off and on for a couple of days and had horrible humidity. Now the hen house really smells and I cleaned it a week ago (have been able to go a week without a problem in the past). Help please, anybody.
