The infection in his foot was deep, and kind of tunneled. I used the curette to dig as much of it out as possible. So, yes I used it inside the hole. Once you remove the scab, then you can better tell the extent of it, and how deep it is. The pus/infection is white/creamy colored, rather than the pink or red of tissue. Some are shallow, some are very deep, every foot is different. I can say, with my chickens, when it's a roo it always seems to be deeper and worse, I guess because they have bigger, meatier feet than the hens. I was very careful and gentle as possible. There may be some slight bleeding, but it shouldn't be terrible. If that happens, just use pressure to stop it. Depending on how deep it is, there are tendons and nerves in there. The curette I showed has blunt edges, they aren't sharp, so kind of like a tiny spoon. There are some curettes that are sharp and meant for cutting, I didn't use one of those. Sometimes a q tip dipped in betadine can help clean it out also, but sometimes the pus is really stuck to the tissue and harder to get it loose. Best thing I can say is take your time, don't rush it. Sometimes some squeezing and manipulation helps get it out. I got very used to it and was able to feel chunks of pus in the foot by feel, they feel like harder lumps than the normal tissue. I used decolorized iodine (not the same as betadine) applied to the scab and then wrapped over night to soften it up before removal, sometimes that works better than soaking. I would work carefully, and as long as he had patience for, and then let him rest, pack with sugardine and wrap, and repeat the next day, until it was as clean as I was able to get it. After I started with the sugardine, I would clean it out daily, and after about a week it became obvious that it was not generating as much pus. It slowly reduced until it was just a wound with no more pus generating. When I didn't see any pus forming I would just flush the wound before reapplying the sugardine and wrapping again. I use a 6 or 12 cc oral syringe for flushing it out, works well for me. I use diluted betadine for flushing, since that's whats going in the sugardine. The sugardine also helps it heal from the inside out, so it doesn't close up at the surface trapping more infection inside so it can regenerate. It did take about 5 months to heal up completely, but it was much, much better sooner than that, it was slowly getting smaller, he was obviously much more comfortable, and definitely on the right track. The duoderm bandages were really, really helpful. You can cut them to the size you need and the box last's quite a while. They really help keep the sugardine in there and moist, and help keep the wound clean. The ones I get (on
amazon) are Duoderm CGF, and are 4 inches square, so you can get quite a few from each sheet, and there are 5 sheets in the box, currently $15.50. You just cut them to a size that leaves about 1/4 inch border around the wound area, they conform to the foot after you wrap it. You peel a plastic cover off one side and that's the side that goes on the wound. Can't recommend them enough.
