Didn't order from Ideal this year, but did for Spring 2011 and was surprised that 5 of the barred rocks turned out to be a "mystery" breed. The good folks at Ideal sent out replacements asap. This was an order of 40 chicks in total, and all but one survived. Good PR as far as I'm concerned, and my neighbor is also happy as the recipient of the five girls in question.
BTW, my avatar bird is not a hatchery bird.
