Thanks for all the info folks!
I checked to see if they changed the feed chart to start weaning him off his alfalfa and apparently they did it a while back. Which sort of irritated me.
In Dec. I noticed he dropped weight. It was very very cold, in the neg's. At that time I asked them to titrate him up to a flake of Alfalfa. Which I know they did because it was to be fed in the morning and I was almost always there and could see he had gotten it.
Anohow, when i talked about weaning him off they said he already was off, so I was a bit mistified how the miscomunication happened.
As of now he is on straight grass hay 2 flakes morn and eve and his other suppliments. He will stay on most all the suppliments when he goes to pasture, but not the same amount. I will talk to my vet about that one when the pasture grass gets better.
I also talked to my Dad and asked him if Tiny had ever had any period of time when he was out with others. He told me he did have about 6 months where he was out with some other horses. My dad is a tb breeder and sometimes sends some of them to other places for short periods of time. I think Tiny was about 3-4 when that took place. Sometime after his stifle surgery.
Another gal at the barn is now going through the same things as I am. She has a 21 year old Warmblood who has some joint and lamness issues. Right now she has him in the barn with a 12x12 stall and 12x24 run. (same as Tiny was in a few months this winter. She is considering putting him into the gelding pasture in March. She just moved her two horses back to my barn.
That would make four of them out there.
Right now he has been sort of weaned off his blankets. He still has a good amount of hair. Since the weather got crappy ( a foot of snow at the ranch today) I told the staff if it gets below 15 degree's throw a blanket on him Preferably a sheet unless it is reall really wet out.
He has met all the horses currently in the pasture. One he knows fairly well now. The other two he has met through the fence and the only one I see him having an issue with is the yearling colt.
I have planned the day for March 2 as I have no school that day and can be at the ranch all day to watch and observ. May even video if I feel up to it.
