How to tell the age of turkey poult?

Hi all, we rescued a broad breasted white turkey poult about 3 weeks ago. We're trying to tell how old she is, but have no idea. How can you tell?

You can usually tell by size. So something in a picture for size comparison may help. Just taking a wild guess off your picture I'd guess 4-5 months.
