What a lovely snake and a refreshing change from live feeding videos, ignore the idiots how have commented negitively of corse you can feed snakes poultry, creepingdeth1981 now whos the idiot!! Anyway, gorgeous healthy looking snake, thanks for sharing :-)
I think you should get your snake to a vets asap - looks like bad scale rot/burns either way the vet will be able to treat it for you.
