i posted about this subject also and no one responded, im glad someone did for you. im using saline eye drops for his eye and washing out with warm water and warm bath and some antibiotic ointment, my duck was on antibiotics a week ago though so i dont know what mine is either im waiting to start injections of antibiotics again... good luck and i do think you should use the saline, as what ever this is its an infection and you want to keep the area clean as possible.. esp if your chicken scratches her face or uses slightly dirtied water... its just to be on the safe side... if not at least wash it out with warm water.
