The chicken became invisible

Beth:	[age 6] "I have to tell you a story."
Me:	"Okay. What's it about?"
Beth:	"It's the story of the invisible chicken."
Me:	"An invisible chicken?"
Beth:	"Yes. A chicken got lost in a science building, and there was some kind of accident, and the chicken became invisible. And then it went back to its farm."
Me:	"How did they know it was there?"
Beth:	"Well, they could hear it. And they could see it laying eggs. The egg would just POOF! appear at the farm, but it was really because they couldn't see the chicken. They could also see it eat and poop but never see the actual chicken."
Me:	"I guess they couldn't catch the chicken either, right?"
Beth:	"Well, the farmer did finally catch the chicken just by grabbing it when it was laying an egg. Then the farmer cooked the chicken, and someone ate the chicken. And that someone was the farmer's wife. And then /she/ became invisible. She was also pregnant then, and her kids were born invisible."
Me:	"Wow, that sounds really weird."
Beth:	"Yeah, and one of the kids had an invisible touch, so everything he touched became invisible, and he touched a hamster became invisible. Then the hamster touched another hamster and made that one invisible too. Eventually everything alive in the world became invisible. That would be a funny story, don't you think?"
