I agree–find a boarding situation for this horse until you are better prepared to bring her home, by adding a “sacrifice paddock” and a companion. If she can’t go back to her old trainer find a new one.
if you cannot turn her out then you need to be riding her every day, hand walking every day and hand grazing, every day.
she needs to be out that stall 3 or 4 times a day, she needs stimulation, she also needs a buddy. even a small buddy in a diff field so she can see them and sense them and yet not fight.
even my very old timer who is ultra sweet and will let the kids jump him after weeks off, would be pissy and irritable on 24/7 box rest and limited work and no mates…my young horse would KILL me in that situation 
She was fighting through the stalls. She was tearing her legs up bad. The trainer never turned her out with the other horses. Always kept her in a small arena alone.
Well it doesn’t sound like she was all that sweet to being with then.
Trainer was worried she would get her legs caught in the rails. She also tore her face up from fighting of some sort. The trainer is not going to let her go back, I am looking for a trainer to coach me through everything around the North Louisiana/east texas area if anyone knows anybody.
Has a vet seen her to possibly get her on regu-mate? Could be hormones that she’s so whacked out about other horses - Have you spoken to her previous owners about this behavior to others? What’s her background?
You might even want to get a vet check, too. Was blood taken in the pre Purchase Exam? She might have been drugged a bit.
Hope you get the turn out fixed but please don’t worry about rain and mud. Our horses are all terrain vehicles! Hand walk her for an hour then let her out.
She came from a boarding facility where she lived all her life, shes 12. They each had their own tiny (maybe 1/8 acre) paddock where they never were in the pasture with another horse. I had the vet come out and float her teeth, pull coggins, and do an overall health check and he showed no issues.
To OP:
It’s starting to sound to me like the ‘trainer’ you mention isn’t much of a trainer or a horseman. More likely just a ‘someone’ who boards horses – and kept this mare in a situation that was better for THEM rather than the mare.
They certainly didn’t investigate the possible causes of the agression she ostensibly has towards other horses – and chose to solve it by keeping her alone/stall bound/limited turn-out?
Blessing in disquise (for you and mare) that they won’t board her again.
Hope you are able to find a different boarding situation – with a horseman.
As others said, the companion doesn’t have to be in the same paddock as her for it to be beneficial. She was turned out regularly where she could see other horses, and saw other horses in the barn. You removed her to a situation where there are no other horses for her to see, period. Hardly fair for a herd animal, of course her temperament changed.
I’ve done a little bit of research regarding companions, i was interested in getting a goat. Anyone had experience with mixing horses and goats? Was it successful?
“They each had their own tiny (maybe 1/8 acre) paddock where they never were in the pasture with another horse.”
And she lived like that for 12 years?
And then she came straight to your backyard? Or was this trainer/boarding situation you mention, an interim stop along the way? I’m confused. 
As far as I know yes. The man who owned her came to the boarding facility in the evenings and fed her. She was rode 2-3 times a week just trail type riding. When she was at our boarders for 4 weeks she was in the stall all day. Only turned out 2-3 times the whole time she was there besides when she was ridden by my daughter once a week.
We bought her early December, she went to the boarders for 4 weeks. She came to our house last Friday, the boarder was worried she was going to hurt herself constantly fighting the other horses so she asked if we could go ahead and bring her home. She moved every horse there (5) in the stall next to Stella (our horse) and she would kick and bite every single one.
Turn out is essential and easy in the South. Our two are in a small sacrifice paddock for the Winter. There’s a 3 sided run-in shed. They stay out even in the recent snow storm. The water tank has a heater to keep it ice free. They are happy and healthy Mud Balls…
I really think that you need to find a good trainer with a boarding facility who can teach you and your daughter good horsemanship skills.
I honestly don’t think at this point it is safe for you or the horse for you to be handling her by yourself.
Was your daughter’s trainer involved with the purchase of this horse? Where is she now?
Please don’t buy a goat or any other animals at this point. Please do find competent help at a decent facility.
Call the vet back and ask for recommendations of nearby trainers.
Contact the local farrier and ask for recommendations of nearby trainers.
Ask your local feed store for recommendations of nearby trainers.
Get thee to a trainer!!
This poor mare sounds like she had a pretty boring but active life as trail horse for a facility with a large string. Why did they sell her?
I agree with others that she needs to be moving. Horses only learn well if they are otherwise satisfied, fed, decent sleep, healthy exercise. You can keep a 4 year old child inside on a sunny day, feed them nothing but candy, and then expect them to take a math test. The horse needs some letting down time to romp about. Walk her or lunge her or turn her out. Just do something. Probably just keep doing that until you get a trainer involved.
You really need a trainer to help you learn to handle horses.
She was, she did not actually go with me to buy the horse but helped us weed through a lot of horses. She has been answering all my questions but I feel like i am asking her 100 questions a day and don’t want to annoy her. I am looking for a trainer.

I miss the edit function.
Thank you all for your advice. I really do appreciate it. I know i have LOTS to learn!
