Olive egger chicks, don't know how old they are

[EllaTheQueen6]

Hi! My mom went to tractor supply for feed, and impulse bought four olive egger pullets. Although I'm very happy to have chicks again (my chickens grew up and they hate me now), I don't know how old they are. They're not newborn, but they're no more than 3 weeks old and I just need help getting a more close estimate. My mom says they didn't tell her how old they were either. Any help is appreciated, please and thank you. (Sorry if this isn't the right board)

I'd guess 7-10 days.
