I get my oxine from revival. Not the best price but I get dog supplies from them too. Instructions are on the product and studies have been done. Search web for latest EPA results and university tests on a variety of nasty cells. I pour small amount into plastic dixie cup then I use an eyedropper 5-7 drops of product for one gallon water. I also pour small amount ( oz or so) into spray bottle add water and use like bleach cleanup spray for disinfecting watering, feed containers and surfaces that get funky around coop or my property.
