We found one of our young hens in the coop this morning with the other chickens stumping all over her. She has a twisted neck to the point that the head looks completely upside down. We thought the neck might be broken. We took her out and she is sitting in a cardboard box right now. She can straighten her neck to be in normal position and has even pecked at some food and drank a sip of water. But then (I guess when she relaxes) her neck and head turn back into the abnormal position. Is this "just" a kinked neck or is is a broken neck?? Chickens don't show pain too well, so we don't know how much she is suffering. Should we kill her immediately or give her some time to get better?!? Obviously, we are not experienced farmers and need some professional advice here. Thank you! In first photo you can hardly see head as it's twisted around. Second photo shows hen trying to get head in regular position.
