My 4 wk old jersey giant has had her head tucked under her wing on and off all day- it's almost like a sharp seizure that makes her neck curve under. Now, she occasionally turns in circles several times in a row. I have her separated. She's eating and drinking and I've started her on vitamins I've read for treatment of wryneck but no other chicken in sick and I can't help but wonder if maybe she hit her head or got hit on the head. Any experience with this? Anything I can do to assess the situation more fully?
