One of my white pekins (who is free range) has been limping for awhile. It seemed to get better and then got worse. She is hard to get close to so I couldn't get a good look until today and I noticed she has bumblefoot. I was able to cut off the black scab over it and I tried to scrape out the infection but it was really hard and I couldn't get much out. I soaked it for quite awhile in warm water with epsom salt before and after cutting the scab off. I soaked a gauze and the open wound with tea tree oil and wrapped it, and put her in a large dog crate for now. I also put duramycin in her water. Should I keep trying to get the infection out or just keep soaking it and administering the antibiotics?? Tea Tree oil was all I had on hand, will that be okay or should I get something else? The infection is in the middle of the foot and it is swollen on the top and bottom, the scab was on the top of the foot.
