Showing is always a worry. The 1 and 2 day shows like Chehalis and Monroe and Stevenson are mostly attended by serious fanciers who keep their birds parasite free and in good health. The fairs, where the birds are stuck there for 5 days with people poking at them and other people's backyard birds next door are a bigger worry. The only time I've had sick stressed birds or brought parasites home was from a county fair. That is why many serious fanciers never exhibit there. (Indianapolis was a huge show and fun, fun, fun, but my birds clearly were not at their best after 5 days of travel.) I guess it depends on whether one is serious about breeding top birds. If you want to breed good birds, you need to exhibit. I always think my birds are unstoppable in the yard, then I compare them to other people's exhibits and realize there are a few faults I could work on. I'm always skeptical of anyone who claims they have show quality anything- and doesn't show themselves. On the forums we certainly hear from lots of writers who sound like they have the poultry world by the tail and the best birds around but, lo and behold, they never have time to make a show....
So, I guess the answer is, if your birds are just your pets and layers, ( and goodness knows there's nothing wrong with that!) you are probably wise to avoid shows and fairs, but, if you really want to be involved in bettering the breed, you can't do it without exhibiting against competition from time to time.
(And, yes, there are precautions we take- like putting on Frontline, and giving vitamins, and isolating birds after they arrive home.)
thank you for the input. I really appreciate it. I am just starting.....but I want to become a serious exhibitor (my goal).
