Two of my chickens have round, flat, black scabs and a bit of swelling on thair feet. I assumed bramble foot, especially after comparing it to photos online. I researched bramble foot surgery, gathered my stuff and had a go. I soaked and cleaned the feet, removed the scab and gave it a good squeeze. Absolutely noting came out, no puss or gunk.... Nothing but a bit of blood. The swollen areas don't feel soft and Squidgy or hard and it's not hot/warm to the touch. Colour is normal. After I removed the scabs I gave the feet a little soak in some saline solution, dryed them off, dusted them with antibacterial powder, bandaged then vet rapped. My question is..... Is this bramble foot? Or possibly something else?
