Barred rock with deformed leg/joint?

[Laylahege]

I have 3 barred rocks almost 7 months old. One of them (her name is Stumpy due to her issue) hangs her right leg out almost all the time. She sits real low and when eating is almost laying down. When she's in her "mating squat" she's curved... She's been like this since she was about 4 months but it seems to be getting worse. She's still able to get on her perch and walk up her coop ramp. Should I build a lower perch for her or give her any special care? She lays normally (prolifically actually) and eats/drinks normally.

Was Stumpy vaccinated for Mareks disease? Chickens with Mareks can lie down this way. Does she seem to be weaker on the right side or be imbalanced and use her wings? Would it be possible to get a good picture of her legs straight on while holding her upright, to see if there might be a leg bone deformity?

She was vaccinated. She doesn't seem to use her wings any more than the other rocks. It is a good idea to get a photo of her being held up. She doesn't curl it up like the other leg but everything feels "normal"

It could be that she has something wonky with the knee joint, or was injured. It is good that she was vaccinated, but that is not always 100% foolproof. Do her legs appear normal when she is standing on her own? Here are some picture in an article about varus and valgus deformities that can happen in just one leg or two, and you can note if any of those look familiar:

Thanks for this, it sent me down a rabbit hole and a found a bit of info about similar malformations. Most are saying they will live a full life with a Few modifications. I appreciate your time.

Let us know how she gets along by updating this thread later on. It is always good for others to see how things turn out for birds with similar problems of their own.

UPDATE: Stumpy has started perching with her leg sticking out. She doesn't seem to be in pain at all, eats and lays normally and still has no trouble getting on the perch. I just had to share the photos, it's kind of cute how she's figured out how to use the wall.
