Popcorn Chickens

My boyfriend brought home a giant garbage bag full of popcorn to feed to the chickens. I'm only giving it to them in small quantities since it is butter-flavor popcorn, but I'm sure a little bit won't hurt them any.

They love it! They seem to like to crunch it up into smaller pieces and then pick up all the crumbs.

I wonder if this will make their eggs buttery tasting (or higher in cholesterol)?
