That is nice
I bet there were two really happy campers out there that day
I got my two out of a rather bad situation too. Snipper, 16 year old QH mare, was about 300lbs underweight, had to survive on two flakes of straw a day, shared with her buddy. He us the boss of the two so he ate most likely most of it.
I started them slowly slowly with adding alfalfa to the straw and a handful of Omolene. When I brought them home after about 10days(had to fence a paddock first), I had them on free choice oathay/alfalfa and Snipper got 3lbs of Nutrena Life Design Senior and Omega Horseshine.
I have pictures here in my album, before, and after exactly one month
