SLW pullets beaks/legs darkening. Normal??

[Ashnicole4]

Hi all,
I am new to raising chickens and I purchased 4 pullets from Tractor Supply. They are now 2 weeks old. They were all labeled as Silver Laced Wyandotte pullets but I have noticed that their beaks and legs are darkening. Is this normal or a sign of illness? Their legs and beaks were pale/yellow when purchased but now as you can see in the pictures they are darkening. Also the 2 darker colored chicks are much smaller than the 2 yellow/brown colored chicks. Is it normal for there to be such variation for the same breed?
Thank you I’m advance!

The two black/silver ones are real SLW. The yellow/brown ones are Easter Eggers and will lay blue/green eggs.

Thank you! I was wondering if maybe they were crosses or something. They are really so different.
