Just keep them separate and observe. Do not medicate. If they can't get over the symptoms, then they aren't strong enough and will always need coddling, so it would be best to let them pass on. I've sold quite a few birds and no one has ever had them become ill on moving them. If they become stressed then sick when you take them home, they were probably weak/sick to begin with.
Taking them to shows is no indicator of the health of someone's stock, truthfully. A breeder in Washington State is responsible for spreading ILT, a very nasty disease, across the state. She has been reported numerous times and though she is actually NPIP, they have done nothing. A carrier bird can be asymptomatic, then when stressed, exhibit symptoms.
