Good job! I would keep the stump covered with neosporin, If it has a painkiller make sure it doesn't have a -caine medication in it (such as lidocaine). -Caine's are toxic to chickens. Neosporin usually doesn't use -caine's, but several other triple antibiotic ointments/creams do, so just check the label. If you keep it covered with neosporin and wrapped to protect it from bacteria, etc., then it should heal fine.
