Just noticed something unique about my blue fawn call drake

[FunnyfarmMidwest]

I was locking in the ducks tonight and noticed that my blue fawn call drake has 2 different colors in both of his eyes. A greyish color and brown. There is more grey on one side. I thought this was interesting and was wondering what causes it. His brother’s eyes are not like this. They’re just brown.

Mareks is not a real problem with Waterfowl.

Oh, okay. That's good then

Not sure of ducks can get it, but odd pupil shape can be from ocular mareks. As long as it's just iris color thpugh, I don't think that's a risk

I think ducks, esp the young, are just adorable. Too much work for me, though, sadly. So I visit the duck threads and smile, smile, smile!

They definitely are a handful. Good thing the duck threads are here. This is the brother his eyes are fully grey... they have the same butterscotch mother. But the father of this one was a grey pied

He has heterochromia. It's nothing bad, just a genetic thing. My turkey has it too

I've never seen that before, but, some vitamins, like Omega-three fatty acids, and vitamin A plays an important role in maintaining eye health. It's possible a lack of one, could cause some ocular discoloration. Genetics is also a possibility,

There are some conditions, like Heterochromia, as mentioned by JacinLarkwell that can cause discoloration in the eye as well.

that’s nothing to worry about, never seen it in ducks but it’s common in cats and even humans (only worry i believe is white cats with one blue eye have a very high chance to be blind, not sure if that applies to ducks)

Didn't know that. I know white male blue-eyed cats are often deaf; it's a sex-linked characteristic.

I do believe he’s always had it and I just haven’t noticed.
looking back at some of the closeup pictures I have I did slightly notice it. I don’t notice it in his duckling pictures but I did notice from when he was around 1 month old.
