Silkies with what appears to be Cataracts


Sep 8, 2019
Hey, I am new to owning chickens, but I have been passionate about chickens for a long time, as I truly love the bird deeply. I am really worried about my 2, 10 week old silkies hens.

When I first got them, one seemed to have a very dull cloudy spot in her left eye. As time went on I noticed that the spot got larger and more cloudy. I was not sure as to whether this was some kind of infection or a cataract caused by Marek's Disease "god I hope that's not the case".
I figured since it was only in one eye and it didn't seem to be accompanied by any other symptoms, it was superficial. Maybe just a pre existing eye injury that was healing..

Then today after looking at her eye, I decided to pick up my other silkie, and noticed the same thing. A cloudy white spot on her left eye. It was dull, but it looked exactly like the other silkies eye did. I am terrified that my sweet little fluffs are sick with something serious like Mareks. Please any information or suggestions would be greatly appreciated.

There can be several different eye disorders in chickens. One comes from high ammonia levels in a coop which can burn the eyes causing ulceration. Pecking can cause injuries and infections. Cataracts can be common and may appear opaque or cloudy. Vitamin A or E deficiency may also cause problems in eyes. A disease early in life called avian encephalomyelitis or epeidemic tremors can also cause eye disorders. Mareks can cause a greying of the cornea and may also cause an irregular shaped cornea which causes the pupil to look irregular-shaped instead of round.
This almost looks like it’s it a scar on the outside. But they both have it on the same eye. I am starting to move away from the thought that it is Marek’s because their corneas look totally normal. I will give them a boost in Vitamin E and A to see if that helps. Thank you for your reply!
