Non emergency… Is there any help for this chicks leg?

[morgan2163]

This barred rock chick will be 4 weeks 5/10. We think when we got her her toe was stuck in a gap in the cardboard, she had curled toe, which we fixed.
We have given nutridrench, tried to see if slipped tendon, tried different hobbles. Nothing has worked.
We free range our chickens, and plan to do the same with her, if we can’t fix the leg, will she be ok to get around? She’s been such a fighter I don’t want to cull her, but don’t want her to have a life of pain either.
The issue seems to come from the ankle? Any insight or possible treatments are so appreciated!!
Currently

When she was maybe 5 days old

Since you've tried all of the physical remedies, perhaps this is a vitamin B deficiency causing weak legs. Try giving it B-complex with at least 50 mg of B-2, 6, and 12. Get it anywhere they sell people vitamins. It can be broken in half and pushed into the beak or dissolved in the water.
