i think you did good with the clotting medicine. Give it some time.  Chicks have an amazing ability to heal.  Keep it separated from other chicks for the time being.  i suspect it will close up and heal within 48 hours.  i have had similar issues and they went on to become big healthy chickens.  
Good luck and keep us posted!
