Bumble foot

Ways to treat and prevent bumble foot, which is recurring on same chicken?

Observation is key. Is there possibly something embedded in the skin? Keeping the birds' living quarters as clean as possible, scrubbing the roosts, etc., watching to see if another bird is pecking at them, are the places I would start, in prevention.

Treating the bumblefoot depends on the severity of the infection, but isolation in a nice, clean space, gently clean the foot/feet in question, with warm soapy water, then coating it with an antiseptic/antibiotic treatment of your choice (I personally would use colloidal silver, topped with an herbal healing ointment and a wrap) and if necessary, wrapping it. Check and dress it daily. Some might use an oral antibiotic, as well.

I have not had to treat bumblefoot myself, but I have read cases which involved cleaning out the infection manually if the skin is broken. Is that true? I'm wondering if perhaps there might still be some infection leftover that is causing the reoccurrence BUT I'm only musing out loud.

I've tried a lot of things.  So far, the only success has been a liberal application of iodine poured on the foot each night, until about a week after the symptoms are gone.  

Depending on how bad it is, this might sting the chicken at first, even the gentle, no sting stuff stings like hell.  The normal, strong stuff the feed shop sells (way more affordable than human iodine and a bit stronger) appears to sting less. Once the open wound heals, there is little to no discomfort and they bird often asks for treatment (comes to me each evening) until the infection is gone.  

Other elements involve cleaning housing, checking environment for pointy stuff.  I found isolation didn't work well as the chicken got depressed and died every time.  But happy chicken, clean house, and liberal application of iodine seem to do the trick.

Thanks a lot! Great ideas, will try!
