Maybe they're ordering the "mixed bantams" from the hatchery. I've seen grab-bag selections of chicks offered at hatcheries. It gives the hatchery a chance to find buyers for extra chicks when the hatchery overestimated the demand that season, and the buyer a chance to get a bunch of different breeds at a reduced price. Which is great if the buyer wanted an adventure, but not so great if you're walking into the supply store and having to guess what breeds are in that bin of little peepers!
