Considering some of the posts that said they got chickens with lice, mites and other problems, I can see why this show requires a fee to sell. Looking at the website, they want certifications of health. One of their pictures shows hundreds of birds in close proximity to each other. If one had a contagion, it could spread.
That might be overkill but it seems like a good idea to prevent people from just dumping unwanted birds on unsuspecting people.
At Chickenstock, there was that family that was buying every bird they could get their hands on. We all knew that any chicken they bought was going directly into the chicken pot. There was no rhyme or reason to the birds they bought. I think that at a show like this, that would not take place.
Thanks to this group, I've learned quite a bit about buying and raising chickens. And as a result, I like to think that I'm raising a healthier flock.
