The only show I have taken any of my chickens to the staff collected eggs laid and sold them at the information counter. I guess they thought they were selling them as eating eggs, but weeks after the show it was in the local paper that the buyer (she went every day and got some, she may have gotten all of them) had hatched them out. The picture was really cute, all these fuzzy butts in a brooder with the proud owner, the story put out as human interest and a Fair follow-up, how this lady had enjoyed the fair and been there every day admiring chickens. Well the nasty e-mails to editor from breeders regarding the theft of genetics and the questioning of the Fair policy on selling eggs without the owner's consent or even knowledge... Yipes.
I had been running all my birds together for months, I really did not care even if she did get a pure bred out of it, but I can see others getting upset. Worst part was it was done, there was no resolution, the show committee stated they would ask her not to show those birds in their reply to the paper. That may have appeased some people but really pointless and unenforceable I thought, and does nothing to address the genetics she now had available to her.
