Alright, so just recently I brought one of my mares home from my pasture half a mile down the road, to the one behind my house, which is an acre big (the other one is six acres). The grass in the bigger pasture needed to be left alone so that it could grow and the one behind my house was full of grass. So I brought her home last wednesday, and ever since I brought her, she wont drink or really eat, and she's nervous and pacing around the pasture ALL the time. I've had her here the last two previous years and she's been absolutely fine. So I thought I would take her out and tether her out behind my shelterbelt and she absolutely loved it. She wasnt nervous, she was eating and I brought her water and she drank it and everything. I also noticed that her manure was very "small" for her size, because normally it is larger than what it was. (sounds gross I know, but you gotta check these things!) So im wondering if she is just not used to the smaller space and that is why she always pacing around and wont drink, or is she stressed out also from being away from wide open spaces? I know horses don't like to be enclosed to much, but when I take her out and tether her, she is perfectly fine and really enjoys herself. What is the problem here?
