I have several hens with bumblefoot. One is pretty bad. There's no puss or plug to clean out. It is stringy and kinda gritty. I've been trying to cure it for a week now and not getting better. I soak with epson salt and try to clean it out as best as I can and apply triple antibiotic ointment. All my hens with it are the lighter weight breeds. Most articles say it is usually the heavy breeds. Sigh.
