What's inside of chicken?

So Ilan was eating a chicken nugget the other day and laughed because he finally figured out what's inside of chicken... DEAD CHICKENS! I had long-suspected that kids don't understand that something called chicken might actually in fact be chicken. Otherwise you could call that nugget a "Happy Nugget" and they wouldn't know the difference. I'm pretty sure they don't yet know or understand that "beef" and especially "salami" actually comes from a cow. I'll let them learn that life lesson in due time...
