I have a buff orpington that is acting kinda weird. She seems fine when she is on the ground except for she rubs her head around alot, like most do just not as frequent as her. She always is preening herself. But the thing that caught my eye is the fact that she runs in circles alot. She looks like she is chasing her tail. But when I go to grab her she just runs in circles under my hand. Then when I carry her she hangs her head super low and rubs her beak between my fingers, and kinda struggles. I know it's natural for chickens to fight a little, but if I let her sit on my hand or something she tries to jump off no matter how high it is. I don't know if I should be worried like it's a worm eating away at her brain or something. But if it is something I'd like to figure out sooner rather than later.
