Teardrop eyes genetics duck.

[Stipenvlerk]

For chickens don’t know how useful it is

For humans but might still help, it has a bit on inheritance

The chicken article is great! Now I know it's called coloboma. And I have something to help me specify my question to my local breeders. Thank you so much!

The eye at one side of my little duck looks like attached picture of a human eye.
The ducks eye is a little less obvious and has the small part on top and the wide part at the bottom.
Again, thanks a lot!
