Looking at the photos in your other thread, do both legs have a knot/lesion? Hard to tell.
Where did this chick come from?
Did the lesion/knot appear over the last couple of days or has it always been there?
Hard to know if the chick has slipped tendon or a leg bone deformity. The oozing joint really worries me.
Slipped tendon can be hard to correct and sadly some chicks do not make it. Chirping constantly, she is probably in pain/distress.
You can try wrapping the leg, but if it's a bone deformity, then usually those cannot be fixed. Can you feel the tendon out of place at all?
