Cross beak can also be caused by nutritional deficiencies or the chick's position in the egg--neither would be the hatchery's fault. If the issue is happening across various breeds, I'd personally suspect a nutritional deficiency (smaller or less assertive chicks not getting to feed perhaps?). If it was all within one breed, I'd suspect genetic.
I've gotten two cross beak birds from Cackle, a Sultan (this year) and a Columbian Rock (last year). I've gotten one cross beak from Ideal, a Kraienkoppe. I've gotten several Columbian Rocks from Cackle, only one had the issue. Same with Kraienkoppe. I've only had two Sultan from Cackle. I'd likely blame egg positioning or nutrition before the hatchery considering the fact that I've had only two birds out of 200+ with the issue. I can handle blaming myself for some issues with my birds.
Since cross beak develops over time, and is generally not noticeable at hatch, you can't blame the hatchery for failing to do whatever-they-do-with-malformed-chicks.
Of course a hatchery would not like to take the blame for crossed beaks.
