Well, a bird I was given by a friend seems to have bumblefoot, so I did the surgery. And I found no plugs, despite the redness and swelling. Plus I'm all paranoid that I'll somehow contract the staph or the chicks that live in the workshop where I did the surgery will get it. And I'm worried that I cut the hen up for no reason since I found no plugs, or that I managed to introduce new bacteria to her foot since a workshop isn't exactly a sterile environment. I did find some little chunks of yellow cheesy stuff, and those are out, but no big plugs like you can see on the 'how to' thread. Oh well, I know I did what I could for her. Maybe I'll try the Tricide Neo approach if her feet still don't heal up.
Anyway, happy Fourth of July! And in better news, Penny had her ten chicks out in the run today, and they were just adorable.
