You have to follow a few steps before entering them in show. I have no idea what you would have to do in Alabama, but here they have to be vaccinated by a vet for ILT before being in a show. You have to register minimum of a week before a show (preferably before that). I cage them for a few days prior to get them used to it while still on their home turf.
As for the feathers, bathe if possible a week in advance. I use dove shine/frizz remover. It gives the feathers a beautiful sheen! Vaseline on comb, beak, legs and wattles is also good. Cut toenails and beak if needed.
