I had this happen. My first horse came as a two-fer but nobody knew it.
I was just a teenager. First horse…poor horse having to try and survive my ignorance and inexperience.
She did fine until late winter when she just looked skinny (a 3-4) and rough…but she had a big belly.She had tons of forage but obviously we were not giving her enough hay over the winter. I was checking her over one day when her belly started jiggling all over. What?? I decided then and there that she was pregnant. Don’t ask me why with my vast expertise I just knew :lol:. We had the vet out and he was pretty worthless. He said she was wormy and not big enough to be pregnant never mind he did NOT palpate her. Well, she presented me with a very pretty molly mule foal about 7 days later. Since nobody would believe me or at least do a proper exam, and I thought she would foal in maybe a couple months not in a week, nature took its course and she had an easy delivery and everything was fine. The mare of course foaled clear at the back of the property and we had to go wrestle Ms. Mule as the mare would not leave her…but would follow her. We stuffed them into a big stall in my Grandfather’s cow barn as it had snowed that morning (March 1). Even the guy I bought her from (a co-worker of my Dad) thought there was no way she could be pregnant. Yeah, there was a jack in the pasture but he never bothered the horses :eek:. The owner of the pasture said that jack would wear those mares down when they were in heat. Would not leave them alone until the deed was done. All of the mares in the pasture were bred.
I echo everyone else. Get the vet out and get her palpated. Your mare doesn’t look much different belly size wise and udder than my mare did. Maybe my mare’s udder was a little more filled but not much. Boy when it was time, everything happened fast. My mare did take a fall onto her side a few days before she foaled. Whether that hastened things, I will never know.
