Thanks for all the advice, guys. I'm taking it all into consideration.
Until I get a job, I can't really get a much more expensive feed. The highest I can go for one fifty pound back right now is fifteen dollars, and I have no money for any type of hay... that's up to my uncles.. we have to sell at least three of our cows each year just to afford our hay throughout winter.
I am, however, looking at a few different feeds that are within my price range... There is one feed that I really like that I fed in the past, but I can't afford it anymore... after the feed store started selling it to more and more people, they upped their price to over twenty dollars a bag. (darned money-grubbers). I am looking at a senior feed, and I'm trying to find a new feed that's high in fats.
I'm also still looking at blankets... as I truly believe that a blanket will help my girl this next coming winter. I'm planning on buying a good blanket and doing a trial run with it this coming next winter... if that doesn't help her weight much, then I'll start looking for other options.
I checked and felt her teeth today, but it didn't look or feel like she needs them done. I felt no rough edges or anything, and she's eating everything just fine.
