I also had two chickens recently with bumblefoot. The first one had been limping for a couple of weeks before we found her. Her foot was very swollen and full of pus. I soaked her foot daily in Epsom salts and then lifted the scab off and expressed pus for about a week. Then I put her on an antibiotic for a week. After about 5 days on the antibiotic, along with soaking in Epsom salts, when I lifted the scab, out popped the plug! Within 2 days she wasn't limping any more. The swelling on the top of her foot took about 2 weeks to go away, but now she is just fine and actually this week has started laying eggs again.
The other chicken had just started limping. I looked at her and both feet had scabs on them. I lifted one off and the plug came off with it. The other one had a lot of what looked almost like damp sand like material. I flushed it and bandaged her for a couple of days. Within less than a week she stopped limping and seems fine. She didn't get antibiotics because there was no pus in her feet.
