SCG--thanks for the details AND THE PICTURES! All before you left for work in the morning too!
I will have another look at the feet, when DH can help me wrestle the 30# tom!, and look for a dark area. I have looked at the soles trying to figure out what I have, don't remember seeing any dark spots. But now I am a bit more a aware of what to look for, I'll look again.
It is quite easy to spot, especially with the swelling. I've found that most don't limp unless the bumble gets really bad, and I've had some really bad (like, embarrassed to show people, afraid the ASPCA will come find me) bumbles.
The tutorial and pics were easy, I had actually posted the same thing in the Maine thread not too long ago...

Did you wrassle the turkey?
It does sound like an awful thing to use a razor, but that is how it's done, and for those who haven't had to do this, believe it or not, when the chicken is wrapped up, they don't jerk away. Once you get that plug out, you can almost see the ease of walking, even with them taped up!
I try so hard to have a lot of shavings where they jump off the roost, but the little stinks will kick it around, so I am always shoving it back to the middle where they jump down in the morning.
Oh yes, the first time we cut into a bumble I couldn't look I felt so bad. Sometimes I can tell it hurts them because they shake in their wrapper and it makes me want to cry. But afterwards they feel so much better it is worth it.
We don't cut too much into the foot, just around the scab and then lift the scab off, squeeze the foot to get some pus out, then irrigate and wrap. Some people dig around in there, we generally don't unless the scab is convoluted or we can't get the scab lifted up and out cleanly. We've rarely had to open feet back up to do more cutting, but we do occasionally. We've found that if you get the scab off and get the triple antibiotic ointment packed in there and keep them off it that it almost always heals... just remember it really does take about 2 weeks.
