O.k., first of all, I really, really hope my mare is NOT in foal---I have no experience with foaling, and don't want another horse! The only other reasons I suspect she could be in foal, are that her belly is very round, and she has lately gotten very touchy about her sides being even petted. There are other explanations for both of these things, I'm sure. She was extremely underweight when I got her, and has been gaining nicely---maybe she gained a little too quickly, and this accounts for her belly being big. I did worm her about 4 weeks ago, but she could still have worms---I'm not sure which one of my horses passed worms after I wormed them, but one of them did. I was told by both people that each horse was wormed prior to coming to my place, but apparently at least one of these people lied. Anyway, I was just curious as to how young a mare could have the ability to become pregnant---not because I want to breed her, but was wondering if it could even be possible for her to have become pregnant before she came to me. Because of her horrible condition, I wouldn't be surprised if the former owner had just kept mares and all together---I never went to this persons place. I know a lot of people warn against buying "sight unseen", but I mainly wanted her for a companion for my 2-year-old gelding, and I knew I was taking a chance, but they get along wonderfully, and she is a pretty sweet horse. So, that's all. My hubby thought they couldn't even conceive at this young age---I don't know.
