Abnormally short legs causing bumblefoot and possible joint issues

[LanaClerk]

So I got this hen, Riba, last summer who seems to have abnormally short legs, causing her wobble around on only the heel of her foot. She has a very lopsided run because of this and we have been worried about any joint issues that may arise because of this. We also treated Riba for bumblefoot only a week ago that was likely aggravated by the way she stands.
It's not an emergency, but I was hoping that someone might have advice on how to care for a chicken like this, as I have been keeping chickens for sixteen years and haven't seen anything like this.

What breed is she and where did you get her? I could be wrong, but she almost looks like a meat breed, which may be why she walks the way she does.

I'm pretty sure she's a production/RI Red. We got her from the same general store as all of our past hens. Didn't think they sold meet breeds, but it's plausible.

She does resemble a freedom ranger

Some chickens have bone deformities that can cause the bowing out or a knock kneed appearance in one or both legs, and those can cause the feet to turn in or out. Those are called varus or valgus deformity, and are very common in meat birds and egg layers as well. Here is some reading about that:
