do you have pics?? there are many different ways to treat it, what i do is to get some ichthamol ointment- it is a drawing salve, they use it with horses to draw stones out, anyway, i give the bird a foot soak, then dab the salve on the spot, wrap in gauze and duck tape, vet wrap comes off too easy, then i give them 250mg of fishflex(cephelexin) is an antibiotic you can get at pet stores, give that for 2 weeks, change the bandage every day, the infection should pop out- it will come close to the surface and squeeze it out, when that is out, pack with neosporin. hope that hasn't confused you- if you can't find ichthamol, use can make a paste of sugar and betadine and use that.
