No, bandaging anything on a chicken other than feet is useless and unnecessary.
What you need to do for an abscess is minor surgery. You will need a one-sided razor blade or Xacto knife. Sterilize it and clean the lump and make an incision about a quarter inch long at one side of the swelling. Then apply pressure toward this slit to express all the pus out. It will be waxy solid. Get it all out.
Take a slender syringe and fill it with Betadine or other wound cleanser, even saline. Insert it into the slit and flush the wound well. Then apply the wound ointment each day. If it swells again, it means you need to clean pus out of it again. So repeat the minor surgery.
