Bantam with injured leg

[Birdbrainz]

Hello.
I have a bantam hen that has been limping. I put her in a sling to offload the leg, but I'm not sure if it is something I can even treat. Please help. She is eating & drinking, stool looks normal.

Age of bird is important to know. How long ago did you first notice this leg abnormality? Have you inspected the foot and toes and leg carefully for signs of laceration or swelling?

Do you have other chickens? How old are they? Have you noticed any lameness in them? Any mysterious deaths over the past year or two?

Yes, that's the same bird. I am still not sure if it is perosis, which is why I was asking a 2nd time, with different pictures.
