I have a JB hen that when she moves she goes in circles. If she's not moving she just sits there with her head down as if she's resting. I have to put her beak to the water bottle end so she can get a drink. When she tries it on her own her head keeps turning and then her body follows. Her feet appear to be bruised. I had a predator get into a pen and pulled a quail to the side of the cage and ate what it could get to. After that I moved all the quail around into safer cages. I suspect she was in the pen that had the predator attack and injured herself. Does anybody have any idea if I should cull or wait to see if she gets better?
