Chicken heads

We went to Joe's Crab Shack and ordered chrcken fingers for Selah. While wating on our food, she asked, "Where's my chicken heads?" "well, Selah, we don't eat chicken heads in Texas." "Why?" she asked. "Well I don't know".... our puzzled 3 year old throught about it and asked a moment later. "Where's my chicken feet?" "We don't eat those either?"

A this point, she's confused and we had to figure out how to explain that we ordered her "chicken fingers" but they weren't really fingers, but more like big chicken nuggets (that looked more that people's fingers). We left out that last part, but it's true. Where do we get these names that sinply confuse our children (and us)?
