I can't imagine in this day and age that it's OK for folks at the fair to collect eggs out of cages? With people having to have their birds certified disease free etc. The only person who should be touching my birds at a show other than me is the Judge, and I'd better see him use some hand sanitizer after he's touched the bird before mine.
To think of some volunteer just going from cage to cage grabbing eggs makes me cringe. I've never shown a chicken, but I show goats and every time someone asks to pet one of my pygmies I want to cry. "No, you can't. Imagine if I set you in a cage and let 2000 people pet your nose, or rub your ears, it would make you a bit irritable wouldn't it?", then I also have to ask them if they had pet another animal, usually yes, and had they washed their hands after? Probably not despite all the hand washing stations. Tell them about how disease is passed from one animal to another etc. By that point they totally understand why they can't pet the animal. I make exceptions for really small toddlers, provided Mom lets me put some Hand sanitizer on them, and there aren't any others around.
But the idea of some stranger sticking his hands into my cage and stealing my eggs, AND possibly contaminating my birds? That would really make me mad!
