Sometimes it's a solid kernal, sometimes it's more stringy and it tunnels through the foot. For those, I've found the sugardine to work the best. The pus is often is adhered to the healthy tissue and can take some manipulation to get it unstuck. My advice is to take your time, work slowly and try to do as little damage to the healthy tissue as you can. Flush it out often, I use a syringe for flushing and use sterile saline or a diluted chlorhexidine solution. Once you get a feel for it, it's easier to tell the bad stuff from the healthy tissue. The pus is kind of like firm cheese, the tissue is more meaty, for lack of better descriptors. If it takes several days of trying, then that's what it takes. Some birds are very patient and cooperative, others not so much. After each attempt, pack it with sugardine and wrap the foot.
