6 month old chicken with dislocated neck, what to do if anything?
Has she always been this way, or was she injured?
Last year we ended up with an oops bantam Polish pullet. As a chick she looked normal. However as she aged it was apparent she had a very bad case of scoliosis of the neck. She did well though. No special treatment was necessary. She would still be with us if it weren't for a fox.
Is her neck twisted as in wry neck (crook neck, torticolis,) or is it a skeletal problem such as keesmom was suggesting? With wry neck it can be a symptom of head injury, vitamin deficiency, or of certain diseases such as Mareks, avian leukosis, or infections that affect the brain. If you think it is wry neck, then treating with vitamins (mainly vitamin E and the mineral selenium) can sometimes help. If it is a spinal deformity, she may be able to live normally, but I would not hatch her eggs.
