How would strawberries do in a window box?

I live in NH and am currently growing some herbs (basil, parsley, oregano) in a window box, and wanted to do some other edibles too like strawberries. My only real concern is whether the roots would have enough depth to grow well, anyone have any tips on growing these guys? I was going to transfer a plant from a hanging pot from a store, any tips on feeding, proper soil drainage, watering, and root depth especially are much appreciated!
