I have a new mare, I have had her here about 2 months, but only by herself and one other horse for about 3 weeks. (before that, there were 8 horses here total). I have noticed in the last 3 weeks, that she lays down more than any other horse I have ever had. Today, I noticed she has layed down alot (probably 5 times that I noticed). She is not in any distress, no looking at belly, minimal rolling, no kicking at belly when up, nothing that really screams colic. I also noticed that when she is laying, she is still eating grass (we have very nice pastures, and they were put on the nicest one today). She ate her grain as usual. I am a new farm owner, life time boarder, so I am a little "gun-shy". Do some horses lay down a lot? I have just never had that experience and I don't want to worry needlessly. When should I worry?
