I think I know. My first guess was the paper. She used the top sheet and it could have been altered to smell, etc. BUT Penn and Teller said it wasn't. Sooooo my best guess is not the paper, but the PEN. A small bit of something on the very tip, would have worn off by the second writing. I'm betting the ink on that little bit is what the chicken was drawn to. It startead by sniffing along the entire table then went back to each paper. Just sayin.
