I have a stud horse that I have been keeping with a mare for two years for her to get pregnant and they think they are brother and sister. Another one of my mares who is hudini when it comes to gates managed to get out of her pasture last year and we found her with the stud horse. I really didn't think they did anything because trooper (stud) doesn't really seem that interested in breeding. But my husband did mark it on the calendar. Last month when the farrier was out he mentioned that Lakoda (Hudini) looked pregnant, I just commented that she was always really wide. Then yesterday at feeding time I was looking at her and she is HUGE! We have never had a foal before so we aren't really sure what to look for. I look at her nipples, then another mares and hers look like utters, where the other mares are sunk in. The date from last year that they were found together was Aug. 18th.
So now what? She had her spring shots just like all the other horses...is that a problem? When should I put her in the stall? Any tips would be appreciated!
