One of our speckled sussex chickens recently started avoiding the roost at night, and would sit on the ground and star gaze; her head touched her back! She was acting perfectly normal during the day time, eating drinking, pecking around, etc... but now she is doing it progressively more often during the day. At around 11am she had already started to stargaze. We think she may have injured herself trying to fly over the 6' fence. Does this sound like a physical injury, or something else?!?! It is weird because it has been a progressive thing, it did not just happen. We will check tomorrow morning to see if she has been eating. So far no one is picking on her, so she is staying with her sisters. Does anyone have any experience with this?
