we have a 4 month old dark cornish hen that has gotten really weird all of a sudden. she freaks out at night like something's attacking her, only there's nothing there. like squawks and flops around. when she was in the coop with the other hens, we thought the big girls were picking on her, asserting their dominance and all that, and my husband actually thought she was at death's door when he checked it out one night, so we put her in the tractor. now we are not sure that anything ever happened (external to her). she is completely safe and even if a raccoon did come near our dog sleeps 30 feet away. and yet she freaks out once an hour, all night long. she is fine all day. so any ideas on what is going on? ptsd? nightmares? if she keeps it up she's going to get culled, but might she have some crazy neurological disease? mad chicken disease? do we even want to eat her? any help at all would be appreciated... :)
