Hi I have a 3 year old part work horse part saddle horse mare. We keep her at my boyfriends grandparents farm, he has a few horses himself, which he does nothing with them, he also has a stud. There is two pastures, but they are only separated by a hot wire on the top and barb on the bottom. We usually try to keep him inside while the other horses are out. But I have a suspicion that my boyfriends grandfather put him out in the pasture beside hers and I think that something happened and he got through the fence, not 100 percent sure. I haven't noticed her come into heat for awhile, along with the halflinger we have. My boyfriends strawberry roan has been in heat since though. Its probably been like two months since this would have happened, maybe not quite, but it has been a while since I seen her come in heat. Would she skip heats where she is younger? Any suggestions, or ideas?
