Which came first, the chicken or the egg?

Apparently, Stella has Tim's genes when it comes to spending time deep in thought about life's most pressing questions...today's question to ponder:  Which came first, the chicken or the egg?

"mmmmm...chicken..."

Deep in thought.

Enough with the arguments on causality, mom...I want to play in the recycling bin again!!!!

What's the next problem Stella will solve, you ask?  Healthcare...
