Smitty, welcome to the flock. What breed/breeds are you interested in showing? Once you have that figured out you might like to post on your state thread (at "where am I, where are you," in the social forum). You may find local breeders with show stock, so you wouldn't have to have them shipped. You would also get to see first, what you are buying.
You could also put the breed name in the search box and see who posts on it, and what they have to offer.
If you search in the Chicken Breeds section of the Forum there is a section with threads about showing, there are likely lots of folks there that would help you out. You may also consult with a local 4-H or FFA leader, even if you are too old they may be willing to get you started in the right direction.
