One of my hens has crooked toes on her left foot, and it appears she has a hunch back. When I hold her her skeletal structure feels much different than that of my other hens. I knew she had these conditions but lately as I watch her I begin to worry about her. Here are some photos of her toes & back.

You can see here how her back is very hunched up...

Here you can see her left foot. I knew her toes were crooked since she was a a month or two old. I wish I had noticed it when she was a chick, I've read it could have easily been corrected.

The right side of her back/shoulders are much higher than her left side, and she walks odd. Almost waddles.

In short I am more concerned about her back. Is this is a deformity she was born with? Did she just grow this way due to an injury when she was young? She is about 3 1/2 months old at this point. I am worried that her deformities may lead to complications health-wise. Do you think she will be able to lay eggs?
I have raised chickens before but have never encountered these problems before. Any advice or opinions you could share I would appreciate.
