I am fairly new to chickens, just a few years, and this is my first experience with bumblefoot. I soaked her foot in warm Epson water and did the surgery to get the plug at the bottom out but it didn't come out as nicely as yours did. It came out in pieces. My baby had swelling between two of her toes as well. I tried and tried but could not get anything else out, no kernel and no puss, nothing more than pieces. So I cleaned her off, put some Neosporin on and bandaged her up. a few days later I checked on her and the swelling between one of her toes had gone down but that was all. So I soaked her foot again and checked her over. I cleaned her off, put some Neosporin on and bandaged her up again. A few days later (today) I brought her in and gave her another Epson foot bath. I took a look and seeing that the bottom looked a little better but the swelling between her toes looked the same I decided that perhaps I needed to go in through the top as others have suggested. I was putting that off because that actually frightened me more than going through the bottom, thinking it would be more sensitive. I took a deep breath and cut a small line in the top. She seemed to handle it better than I did. I gently squeezed and to my surprise I did get something out that looked like a kernel and some puss. I soaked her foot again and tried to get more out. When nothing came out I cleaned her off, put some Neosporin on and bandaged her up again. I have a good feeling that this will resolve her problem. Thank you all so much for your invaluable knowledge. I love this forum!
