One of my chicks is doing this weird hula-hoop/figure 8 motion with her head. My first instinct is that she is adjusting her crop? She came home (from my son's classroom with some other chicks) today, and they all hit the feed like they had never seen food before. That's when I noticed the head/neck motion. She seems otherwise healthy, I think. Normal poo. Any one experience a movement like that before. Almost looks like a dance ...
