Black Star earlobes turned bright red??

[swakita]

Hi all! I have a 6-7 week old black star that I believe is a hen. Seemingly overnight her earlobes turned bright red… I have another black star that I think is also a hen and her earlobes are still an off white/light pink color. Are the red ear lobes concerning? I’ve attached a picture as well!

She's just maturing more rapidly.

I have 4 Black Star pullets with red earlobes. The fifth has white earlobes. I just accept the fact that these are not a pure breed but have a little ‘this and that’ mixed in over time. Is there a true 100% anything? They do have the green iridescent color and wonderful friendly personality.
