Hello can someone please help me figure out what breed my chicken is?

[terrycat17]

She looks to me to be Rhode Island Red or maybe a Buckeye chicken, I am not exactly sure. Here are some pictures:
Here she is eating grass.



Here she is laying an egg.

Here she is exercising.

Thank you for your time.

Rhode island red or red sex link, I am awful at guessing breeds though but those are my guesses

 

[Rhode Island]

She could be a Buckeye or Heritage RIR

I think Rhode island red cause buckeyes has a pea comb not single comb

Then in that case they might be Heritage RIR
