Hen not laying

[burb120]

I bought this hen from a craigslist add and the previous owner seemed honest about the chickens, but he claimed she was a year old. She is not laying, is there any way to tell how old she is. I have had her for 2 1/2 months and she acts young and likes to run around a lot, she also is mean to my other chickens sometimes, but if anyone knows how to tell the age or has any suggestions let me know.

She does not look like an aged hen. I would guess that the change in homes and shortening day length have combined to stop her egg laying. She will lay eventually.
