I do not know if she was cast for sure, I was only assuming because she got herself cast against the side of our barn in the quarantine field (layed too close, tried to get up and feel back down and got stuck). She does lay down and nap quite a bit. I have absolutely no history on her.
She does seem stiff in the neck, she can flex it when we ask, but does not do so on her own. She generally walks with her head low and doesn't turn her neck much if she turns to look at something. None of her feet are clubbed, but yes her hind foot is quite turned out. That is the foot she rests the most. Another thing she does is stand up on her toes and stick her tail out (looks like she is about to pee)- she does this if she has been napping in one spot for a while and I have caught her and make her walk forward. She also would do this when I was trying to pick up her hind feet at first, she would refuse to pick up her foot or pick it up slightly then stand on her toes - she has really not done this lately.
We have not done x-rays. We had the vet look at her the second week we had her and pulled blood. We started out with the lyme test first, when it came up positive we opted to treat her first before moving on.
I honestly do not have a lot of money to invest in her. And yes I do already realize it was foolish to buy her without having loads of cash sitting around in case there was a problem. I guess we were just seeing and animal that needed some food and tlc, not intensive veterinary tests.
