In Gail Damerow's book, The Chicken Health Handbook, she mentions slipped tendons can be from a deficiency of manganese. If that is the cause, it will clear up in a month with proper supplementation. Sounds like you want to give this baby any chance it has. Thank you for not dumping in the "trash" but considering it might be able to be helped.
Wishing you both luck. Know how hard it can be when they are born with challenges.
