I've successfully treated some life threatening infections and diseases via natural methods including demodectic mange. (Apple Cider Vinegar baths fixed that).
About the chooks: it's possible that its a superbug that's immune to antibiotics. In this case the only remedy is the equivalent of chemo which could cost you the chook, or going back to natural remedies which are extremely hard for the 'bug' to become immune to. I would use raw freshly minced garlic in their diet to tackle it from the inside and I'd bathe and soak their feet in garlic brew, maybe with other antiseptic, vermifuge, antibacterial and antibiotic herbs. (Wormwood, sage, rosemary, oregano, etc... There are many).
Or I'd try Stockholm tar. I bet you that would do it. It's worked on gangrene and antibiotic-resistant golden staph.
If you're interested in trying it, the raw garlic in their diet can be a minimum of one clove per bird per day, the herbs can all be a sprinkled pinch per bird per day (very little needed in such small animals but overdose not a concern unless you're forcefeeding handfuls day in day out for a long time). Stockholm tar is simply pine boughs and wood, especially roots, boiled until the resinous tar is all that remains.
I know going against the pharmaceutical remedies can seem utterly foolish at best and outright insanity at worst, but despite my initial skepticism it has always worked for me. Sometimes it seems far too simple to possibly work and I've lost animals through not believing a natural remedy could work where man made ones fail.
Best wishes,
