None of my hens have dark eyes, and none are BSLs.What other black chicken breed do you know of that has paler eyes. The majority of them if not all have dark eyes, that's why I think black stars eyes are different. You may not be able to see that but I can, and if it makes my breed guesses more accurate than I don't really care what you think.
And here’s a Black Sexlink with dark eyes.
Eye color typically has nothing to do with breed/cross.
It’s not very accurate.
And BSLs are a cross of Rhode Island Red and Barred Rock. Both those breeds have medium orange eyes. Where on earth would their chicks get “different” eyes?
