Dan, I have read that the clear iodine goes on once, then is checked again after several days. Do you apply it daily? I am interested in learning how it works out. I use it on myself, the clear iodine - but usually early on, before there is much infection and so I don't get the dramatic result that Haunted55 wrote about last summer (I think that's when I saw that post).
PierceFam, what are they walking on?
Amiga,
When I find a bumble on one of my Little's, I start by soaking their little feet for 7-10 minutes daily (or roughly 2 songs on my phone - it's always in my pocket playing music when I'm out with the duckers) for a week or so in Epson salt water.
Actually, lately I've had 2 of my 5 with mild bumbles, so everyone has been getting 'spa treatments' this week!
I've also modified their pen flooring by adding a layer of perforated rubber stall mats over the solid rubber horse stall mats already in there - my thought being that they have had too much contact with flat wet, duck poo (read bacteria laden) floors.
Squirt checking out the new 'improved' pen flooring:
Even though I thoroughly wash the pen out twice a day, they still tend to muck it up pretty quickly, and the new perforated mats allow the water and poo to drop away from having so much duck feet contact.
I've gotten all off topic....
Back to your question, if the bumble is bad (large/nasty looking/discolored/etc), I'll put a drop of discolored iodine on the surface of the bumble daily, and also apply some 3in1 antibacterial ointment over it. This is after the Epson salt water soak. My reasoning is that I'm using the Epson salt water soaks to bring the infection out, and the topicals to keep the surface/sub surface bacteria in check as much as possible.
Because I never 'operate' (at least haven't had to yet) on their bumbles, the skin is not broken per-se, and the iodine and antibiotic ointment are being used topically only, and only on the bumble.
This may well not be the best method, but it seems to work on my Little's... Hope this helps!
Dan
