Tomato Hornworms in the Vegetable Garden

Today I noticed the tomato plants were being eaten by something, after looking a little closer I found 2 large tomato hornworms.  They are actually really cool looking - if it wasn't for them devouring our tomato plants I would not want to get rid of them.  If I were to let them live and eat our plants they will eventually turn into a Gray Hawk Moth, an equally creepy looking - giant moth.
Looking really close it looks like they have tiny eyes along their side, I'm not sure but I think these may be the spiracles?
Creepy and awesome!

Since we can not let these hornworms live, we decided to feed them to our spoiled hens - Here is the video (caterpillar lovers beware!!):
