Update: Not very much poop, it's white and looks runny. This morning she's not eating unless we dribble it on her beak (then she gobbles it) and she's also started doing somersaults backwards. We're trying vi-sol, vit E, & selenium.
Should I put her back outside with the other three?
1) What type of bird , age and weight (does the chicken seem or feel lighter or thinner than the others.)
Australorp, 1 yr, not sure but does feel lighter than usual
2) What is the behavior, exactly
Looking hard right, spinning very slowly in place or staying still with extreme neck angle.
3)...
