Cute cute.
Does Winky have an eyeball? Looks like it....is the eyelid not formed right maybe? I had a turkey poult last year that had an eyelid that wasn't formed right, looked somewhat like that....
My other thought is maybe he just has a dirty eye and needs to wash it.... I don't think I've ever seen one get that way that early on in age, usually takes a few more days, but anything is possible I suppose. lol If it is just a dirty eye, it typically clears up when they're allowed to have enough water to submerge their heads.
I see you raise ducks, so that may be old hat to you though.
