That looks like what it might be. She has female specific feathering. The male's would be lighter colored and barred. Should be an auto sexing breed and able to tell males and females apart at hatch.
I did a Google search using that picture and it did come up that but I'm not sure how good Google is as I tried with a picture of same bird when it was week old and it said it was a Japanese quail lol
She could be a Legbar, or she could be another breed that looks similar. A lot of different breeds have that same dark chipmunk look when they hatch, and I can’t tell from the photo if she’s got barring or not. Also it almost looks like she’s got the wrong comb type. Legbars have single combs, while she appears to have a pea comb. I could be wrong, but a head shot would confirm what kind of comb she’s got.
Well, she does have a single comb, but I’m not seeing any barring. It can be pretty faint, especially in pullets, so it’s still possible she is a Legbar.
Does it look like she is developing a crest? Gold Legbars do not have a crest (they were developed from crossing Brown Leghorns and Barred Plymouth Rocks). They will lay white to light colored cream eggs.
If she has a crest, she is a Cream Legbar and will lay blue eggs (as long as she is a pure Cream Legbar.)
