I just started using oxine.They get 8 drops in a gallon of water a day and 6.5 oz in a gallon of water misted over them three times a day.I have been doing this for a week now becasue I have two that are sneezing.I still hear them once in awhile.I can`t do it today as its below freezing in the coop(the misting part).How long should I continue this before I notice no more sneezing?I also spray the coop with the misting to.Anyone else use oxine and for what and how much do you use???
