Duckling leg problems

[hunterdan97]

I have a pekin/indian runner duckling that hatched Tues evening. Normal natural hatch - my ducks are actually sitting on eggs - although seemed to take a long time. I've had leg issues before, but have found they normally resolve themselves over a 24h period. This particular duckling is basically unable to sit, stand, do anything but roll around. It's legs are straight out the back end & its feet are all curled up instead of out in a normal fan shape. It is drinking & eating with assistance.

Is there something I can do to fix it or is this something that will not get better? Feel like I'm torturing it...
