heterochromia? or something else?

Have you ever spotted a feathered friend with eyes that seem to tell a story all their own? It sounds like you might be witnessing heterochromia, a charming condition where a chicken has two differently colored eyes. In your case, it could simply be a unique quirk of your pullet's genetics, especially since she’s healthy and showing no signs of vision problems. The striking dark color could be a natural variation, rather than a cause for concern. However, if you're still puzzled, keeping an eye on her overall health and behavior is always a good idea. After all, our feathered friends can be full of surprises—just like the mysteries of their marvelous eyes!
