What breed is my ~7 month old hen?

The pictures might be a little low quality, apologies. We were told that she is a Leghorn-Delaware cross, and she just laid her first egg today(yay!) but it came out... an olive green color? Any thoughts?
(Brown egg on the left is one of her sisters')

My guess is that she's an Easter egger/Delaware cross. Pretty color to that egg.
