I'm sorry to say, Ike passed away rather unexpectedly for no obvious reason. I certainly suspect it was the disorder/deficiency behind it. We just found him on his side, dead. I know deficiencies and imbalances can lead to heart damage. I feel that may have been the killer. He was never able to walk right and scooted/flapped along. He never seemed bothered by it much, or in pain. He always ate very well. I would do physical therapy with his legs to give more movement, and he did seem to benefit from that.
His hatch mate Tina, has been thriving though. Her symptoms were not as severe. Her gait is a little jerky, but she has been accepted by the flock and seems content.
Hydration, supplements, warmth and low stress seemed key during our struggle. Good luck, its a tough call.
