I have been searching for information on slipped tendons and broken legs without much success. Yesterday my husband was clipping feathers on our birds to keep them from flying out of the run and apparently sometime when this went on my one year old call duck hurt his leg. He can move his hip, but the problem lays in the hock area. From there on it foot doesn't move. I felt both legs comparing for differences and neither my husband or myself could feel anything different. Any suggestions?
