Those wounds are really not the worst I've seen.
Clean the wounds with Peroxide to get out the initial infection then clean with a Betadine scrub. Then, apply Neosporin (or Triple Antibiotic ointment) LIBERALLY all over. Do NOT stitch or close the wound. The skin will eventually grow back.
All of this will cost you MAYBE $10.00 and is handy to have around for the "just in case" factor that is always associated with chickens.
