Wing sexing 3 day old seabrights

[Zoemay]

Hi all,
I have three silver seabrights which have hatched 3 days ago. I noticed two have different wings to the third so asking for some advice. This first chick has longer feathers at the end of its wing same as the other

And the last chick has nothing

Any indications would be greatly appreciated! Thanks guys.

I don't believe that Sebrights can be feather sexed.

Wing sexing wont work. Wing/feather sexing only work with very specific hybrids.

They are currently way too young to sex

Feather sexing only works with specific crosses.
