I found my duck holding her foot up just over a week ago and a tiny bumblefoot scab. I started her on Baytril, soaked with epsom salts and scrubbed the scab with iodine a couple times a day. Now the scab is pretty much gone, but the swelling is worse. I just got an epsom salt poultice that I am trying on her foot overnight and wrapped, but I also had it on today with no effect. What is the best next step in this case? Photos are when I first discovered the infection, and then one week later after the antibiotic and treatment.
