I'm very worried about my polish hen. She has been limping around for about a week and a half. Both legs are rather swollen and the left seems to be bent. We have examined both feet and there appears to be no obvious injuries. For what it's worth, when she was a chick, she had a bad case of wry neck. She recovered from that illness and we don't know if there is any connection to what's going on now. Please help us help her.
