The hatchery should have pics. If from a hatchery you only have limited breeds they could be. Meyer hatchery has on online chick ID guide for their chicks, maybe the hatchery these came from does too.
Does the "hens choice" come from a set list of options? I don't see any obvious hatcheries that use that term, but see it on a lot of Ebay hatching egg listings.
To answer your original question, Google is the best for photos if you know what the options might be. Just plug in "xxx chick" where xxx is the breed and you will find tons of photos.
