For those who show your chickens: integration back into flock?

This question is for those who show your chickens. How does the re-integration of your chicken to the flock go? I've never shown, but have had to separate chickens who are injured/sick and the separation and re-integration process really upsets the balance of the flock for about a week or two. Does this happen when you remove your show chicken and then re-introduce them back into the flock? I would assume it would but I don't know. Do you have methods that you use that minimizes the stress of removing then re-introducing chickens regularly?
