I have a hen that has broken her femur ( sp?). I took her to the vet and he put her leg in a sling. She can't hop around too well and therefore sits in the same spot all day if I let her. Her appetite is decreasing and she is breathing through her mouth as if she were in distress or pain. The vet gave me pain medication "Metacam" but I don't think it is working. Can anyone help me with some tips or advise to help me keep her going and on the way to recovery. I am afraid she is going downhill from here.
