We have used Green Goo to cure our ducks of bumblefoot. Thankfully, we’ve only had to deal with this problem a couple of times, but we soaked their foot in a warm water/Epsom Salt soak for a few minutes, dried it and then applied Green Goo. Within 20 - 30 minutes, there was noticeable improvement! Only one of our ducks needed a second treatment, and all of our ducks were completely cured by the next morning. Green Goo is AMAZING stuff and we are SO thankful to have found it!!
