Hi Peter, How big are your chickens?! I've never seen ours swallow anything quite so large...but I'd like to see them try...

Has anyone else encountered these or come across a publication identifying and describing these? Everything I've seen only deals with typical stone versions, not ceramics. I've uploaded a photo of a few examples on Zoobook: http://zooarchaeology.ning.com/photo/albums/gastrolith Thanks, PeterThis message and any attachment are intended solely for the addressee and may contain confidential information.
