I found 2 hens that didn't make it into the coop before the auto-door closed. They were huddled together by the door - one on top of the other. I opened the door and shooed the one in. Then I looked at the second one and it looks like her head is on backwards. I picked her up and I can turn her head but she can't hold her head up and it just kind of flops over to the side. Is this a broken neck and what can I do? She moves around but doesn't appear to be able to see where she is going. I have 30 chickens - 29 hens and 1 roo. All seem to be healthy.
