20 muleteam borax the laundry detergent is amazing for yeast problems, put it on there food and dilute in spray bottle and spray topically or in ears etc. its a safe mineral to ingest and non toxic in doses of 1 tsp or less per day. ill usually sprinkle the food lightly and spray topical, but for the first few days ill put 1 tsp in some bbq sause or something to cover up the taste they will lick up quick. Sometimes you have to get them off corn to thats in most feed
