Chicken with a torn ligament, HELP!

[Megchickenlady]

Hey everyone I have an Olive Egger pullet that somehow hurt herself. She’s still in a Rubbermaid tote in the garage so how she injured it I’m unsure. She won’t put weight on left leg. Does not appear to be in pain, she doesn’t act differently when I’m moving and checking along the joints. It’s not dislocated. No external or internal rotation. No bumble foot. I’m thinking it’s a ligament issue as her lower half of the leg seems almost floppy Tib/fib down. Her toes don’t even grasp or wrap around my finger. I’d like to make some sort of splint but is that even helpful or what am I looking at long term prognosis? She’s so sweet. Just want to give her the best shot I can. I appreciate any help or feedback.

Whatever happened? This sounds exactly like my hurt chick right now
