Speckledhen wrote this on another thread, "Soak it, clean the surface and the xacto with alcohol, wrap a towel around her middle so she can't flap her wings and just go around the edge of the plug with the xacto, then use tweezers to carefully pull the scab and underlying attached stuff out, soak her foot again with epsom salts or watered down iodine/betadine "tea" water, dry the foot, pack with triple antibiotic ointment, gauze pad over that, wrap with Vetwrap/stretch gauze (not tight, though), going between the toes and ending up around the ankle. Or you can use strips of sweatshirt material about 3/4"wide and at the ankle, wrap with first aid tape. Keep her out of the wet, maybe in a dog kennel, for three days or so, remove and replace the bandage. Do that every three days or so till it seems well."
This is the best procedure and treatment that I can quickly find. Good luck.
