Limping 7 mo. Barred Rock Chicken

[Wyorp Rock]

I've attached two pictures, one close up of the hock and another of her leg. Her hock does have scabs from her sitting and laying on it the past two weeks. The black spots in the second picture seem new to me.

After a bit more digging here and on a few other threads, I suspect its an Achilles tendon dislocation. Between her limited range of motion on the leg, as well as the flatness of her hock this feels right. I tried some of the remedies for that - stretching and attempting to get the tendon back in place - and we'll see. She seemed to enjoy the stretching, even almost falling asleep while I was doing it. After doing this for a few minutes she was able to straighten her leg but still wasn't putting pressure on it or using it. I'll keep this up for a few days and see how it goes.

If you have vet care that is always best.
I would watch that sore spot.

If the tendon is slipped, you may not be able to fix it due to her age. Sometimes a leg deformity may cause it as well. It's good that she seems to respond to your stretching the leg though.
Have you tried splinting the leg?
