I purchased a gallon of Oxine (sanitizer and disinfectant) some time ago - never used it but understand that this stuff is good for disinfecting your chicken coop - the label says that you should activate the stuff with acid crystals which make it stronger - my question is - can you use it without adding the acid crystals and will it still help disinfecting the coop - also how much would you add to a gallon of water - thanks - Joe
