If they are tumors, it could be from a virus such as Leukosis or Mareks disease, both common in chickens from affected flocks. She may live for awhile and do okay. I would try to clean out the ear, just in case there is some infection inside it. You can use some drops of hydrogen peroxide, and cotton applicators or clean it out. Antibiotic ointment can then be applied into the ear canal. Sorry if she may have tumors on her.
