Oh my! It must have been something like a feather cyst.
@Eggcessive or @casportpony may have a better idea.
If you have vet care that is always best.
My thoughts would be to flush it out with betadine. I have a feeling those started feathers that are inside need to be pulled out as well.
Pack with triple antibiotic ointment and wrap.
Soak daily in epsom salts, betadine or chlorhexidine, reapply your ointment.
It may be tricky to heal, but then again, chickens are amazing and can recover from a lot of things.
See how it goes, but I'm one that would be inclined to consider an antibiotic as well, but lets see what the others think.
