Wouldn't have given any thought to a chicken's tongue, but I snapped a picture last night that got me curious. I tried and tried to research online for in depth chicken anatomy, but darned if I can't find anything relating to their tongues. What are the spikes for? Not the pointy tip, but the spikes farther back in the mouth. Please forgive the graininess of the photo. This was cropped down from 100% of the actual size of the image. Thanks for looking.
