Yes, Easter Egger. 100% certain.
Are you sure that is a girl? How old is the bird?
The coloring fits a roo as it is patchier, and that comb is large for a pea comb? (hard to see in photo comb type)...but if that is an older bird, that would explain the comb.
However, I also see some spikiness in the saddle feathers. Unless that bird is laying eggs already, I wouldn't be too quick to call it a hen.
