White chicken. Help identify

[AhaCoop]

What breed is she? She’s not growing super fast like a cornish cross but she does look similar.

 

[Cyprus]

She looks like either a white Leghorn or a white Plymouth Rock

Can you get a pic of the bird standing on its own in better lighting? I can't see enough of the chicken to determine its body shape or how it would stand.

 

[Gray Farms]

Need a broadside, standing pic. Also need to know what type of comb it has. And an age of the bird.

This was my white leghorns about 4 weeks old
and here about 2 months old, it looks like you have a Leghorn
