Any thoughts on these genders?

These 2 are from the first time I ever incubated eggs. They both are white leghorn mix and the black ones tail feathers and such have grown faster than the other chick. Any thoughts? Thank you for reading!

Too young to sex. Wing sexing only works for specific crosses.

Not wing sexable, too young

I agree with the others. You can only wing sex certain crosses. You'll have to wait until they are at least 6 weeks old to tell.
