Viruses of which there is no cure are the main concern since chickens can carry those diseases without showing symptoms. One is taking a chance with their birds whether they are bringing them to shows or raising them on range. Much more at risk in poultry shows in my opinion. Immunity is more likely on range since chicks are gradually introduced to the environment by those who know how to raise them. Not so at a show even with mature birds where it is a sudden exposure to a stressful environment and birds possibly carrying air-borne viruses. Chicks are rarely seen at shows for a reason; too likely to contract viruses due to an undeveloped immune system. Brooding pens are even safer, when managed properly, for a hen to raise her own chicks.
I have all sorts of wild and migratory birds around my property and have dealt with Marek's virus in the past. That is why chicks are vaccinated for it. Besides that, the wild birds do not pose a threat due to a properly fenced and covered yard. People who allow feeders to be gathering places for wild birds to crap in all day long invite problems. Out on range, wild birds such as quail, finches, jays, cardinals, woodpeckers, warblers, and canaries never prove to be a threat. Control of rodents by keeping feed picked up at night, storing feed securely, taking advantage of appropriate bait locations, following worming programs, proper coop and yard management should be routine to avoid problems.
If anyone is considering going to a show to buy birds, I would say don't based upon experience. If you know what you want, contact a reputable breeder who will be attending the show. Arrange to get birds that have not entered the show area. Of course, for the newer folks, if you have other birds at home, follow the standard of quarantine and close observation for new birds at least 30 days before allowing them in the vicinity of your other birds. You'll be glad you did if any of the new birds have something contagious.
