If a bird decides its going to molt, from my experience, there isn't much you can do to stop it. You can increase their protein and hope to bring them out of it sooner, but I do not do this. Usually at the shows, I will walk around looking at the other entries, talk with other breeders, look over the sale area, check out the silent auction items, ect. ect. ect. They will usually have a small concessions area. Shows are a good time to meet other poultry fanciers, especially others in your area. Being new to poultry shows, I am not sure how much you know about your birds, but even if you are up on your game, I find that it is always a good idea to watch the judge with your birds (From the next isle over). A lot of the times they will talk the class as they are judging them and you can get good pointers as to what your birds has (the positives) and what to work on.
