Crowing
Yes popcorn kernels are fine to feed to chickens, but the chicken needs to have adequate grit in the gizzard to grind them up so they can be digested and pass through. Without grit, nothing will move through the gizzard. But you can't force a chicken to eat grit, they have to figure that out on their own. It seems that this bird didn't figure out that she needed to consume a few pebbles.
