Butterball has a big, fat mystery on its hands this Thanksgiving season. The company says some of its turkeys wouldn't plump up in time for Thanksgiving this year, and it doesn't know why. CEO Rod Brenneman says it's the first time this has happened, and the company is investigating. Brenneman says:
"It's a really good question. We don't have an answer yet. For whatever reason, they just didn't gain quite as well this year."
