Def could use an amputation. It is a fairly quick healing issue and fairly easy as long as it is done while the area is small.

Be sure to keep cage VERY sterile and keep humidity low until fully healed. I would wait on antibiotics as many things are building resistance. Silvadene is a great ointment and will work nicely for healing. Healing usually takes about a week.
