21 week old Hen walking on curled toes

[Jacobt]

My speckled Sussex hen has been healthy, however, in the past few weeks I’ve noticed on one of her feet she walks on curled toes. They don’t really open up, and she just walks on her toes curled in a fist (only her left foot). Is something wrong with her? My other 2 hens are healthy. Thank you!

Is this something new, or has her foot always been curled?
