You might post a picture so that we can get a better idea of what is.
Does it look like there is any drainage coming from inside the ear? They can get smelly and infected. There is also a fungal infection called favus that leaves a whitish gray chalky residue on earlobes, combs, and wattles. Here is a thread with a picture of favus: https://www.backyardchickens.com/t/450401/my-rooster-has-favus-help-please
Sorry I will. And also no there is no drainage coming from the ear. But the one eye where the earlobe is infected.
Her eyelids are swollen and her pupil is facing down and that one eye has lost all it's color? Only the one eye??
