The hen who finds the hunk of "food" thinks to herself, " Wow, this must be really delicious - everyone is chasing after me for it." The other hens think, " Wow, That must be really good - she is trying to keep it all for herself."
Your photos capture their antics well. But I also love the sound that they make when running with food. My Ruby rooster found a little toad once and ran around with it, and he made the sound that maybe could be described as a cross between a whine and a growl. He is usually good at sharing with his hens, but he just wasn't sure what he had found.
