Recently a pair of Demoiselle Crane had a chick, it was al healthy right from the very beginning, its parents used to feed him/her a regular diet which usually consisted of insects and worms, it is almost a 30 days old however since yesterday he is not standing or walking on its own legs but just sitting on the knees
Your baby crane might have stepped on something, But this is nothing like malnutrition, From what ive learned the crane may have a joint dysfunction in the knee but this very common in cranes, I really think you should take an X-ray of the cranes legs because,(and the baby cranes feet will expand over time) This could get worse. This is more than likely a leg dysfunction. Hope this helps.
