Check the requirements of the shows you wish to participate in. They should have rules and guidlines for out of state birds. Most likely you will have to have a recent certificate from a vet, current within the last 30 days, stateing your birds are healthy. Possibly a NPIP certificate and or a VS 9-3 form. Small shows might not ask for anything, but if thats the case, I would shy away from them and not take my birds there. A couple of years ago, the Asheville NC show quarantined and eventually destroyed a bunch of birds because one person brought in sick birds that infected just about everything there. Needless to say, there where a bunch of angry bird owners that saw their show birds wiped out.
