Irregular pupil

[godzillaandfriends]

I've noticed my hen, Dale, has an odd "goat" pupil.
Her other eye appears normal. Any ideas?

I actually think both eyes look abnormal. An irregular shaped pupil, which is from changes in the cornea that makes it look irregular, and a gradual fading of the iris color can be a sign of the ocular (eye) form of Mareks disease. Have you had any others with something similar, or any unexplained lameness or tumors? Do you know if she was vaccinated for Mareks?

No other symptoms, and I'm unsure if they vaccinated her. I got her from TSC, who got her from Hoover's. There is no history of Marek's in my flock.
