Yep, I think the big thing is because people relate more to thinking they get a purebred chick, yet at the same time they don't care what its quality or geneaology is. It is like how people want "purebred heritage" breeds like Barred Rocks and Rhode Island Reds, yet they go to a hatchery, not realizing they're getting run of the mill production layers like everyone else has. But in the end they don't really care. They want egg layers. Which is funny, because then why else are they asking for heritage breeds? The same reason people want "organic" foods. . . For the image it gives them.
