Hatchery silkies are unlikely to be anything more than pet quality. If you picked up from Judy, did you ask her to tell you about the birds and show you what to look for and to avoid?
It's much easier to go over a bird or birds with someone who can show you traits and why they are good, bad or whatever.
Silkies are well enough developed in all the recognised colours that crossing to another breed is not a good choice unless you are working on an unrecognised variety and need to bring in new genes.
If you post photos we can try to tell you what you have,and the good and not so perfect points of each.
