We have two of our ducks with bumblefoot. We have been treating their feet for 3-4 days soaking in Epsom salt, spraying with Vetericyn Poultry Care, applying neosporin original. We have started putting on PRID and trying to wrap their feet but they get the bandages off in about 20 minutes. We're thinking about bringing them inside a closed off area at nights to monitor the wrappings. I have included some pictures of their feet. When should we see a vet? Thanks in advance!
