I have a Dominique hen 12 weeks old), who I found yesterday not being able to use her left leg or foot. She has no control over it. There is no wound or bleeding or swelling. She does not seem to be in any pain, but she can't get around or control that leg at all it just goes out from under her or dangles straight down if I hold her. Could it be dislocated? Is this fixable if so??? Thanks for any advice.
