There is a nice video we watched about showing poultry for 4-H. Perhaps it is available through the 4-H website for your state? Our poultry leader showed it to us.
We are new to this as well. My girls are in primaries, which is non-competitive. Competition starts in 3rd grade (the fair following).
4-H is a learning experience, so if they aren't "big on standards" then I I'm fine with that, personally.
Have fun!
