We have a Golden-laced Whyndotte who has had very large bumbles on both feet for a long time (a few months). We have tried a lot of different things: Antibiotics, essential oils, Epsom salts, surgery, Black Ointment(pine tar with herbs), Blu-kote, and Nu-stock (what we are currently using). They have not really improved at all. Any ideas of what we could do to help her? They are both a little larger than a pencil eraser.
