Today, I watched our mini stallion suckling from the more timid mare. She allowed it and it continued for some time. Is this normal? I tried googling, but didn’t find anything useful/actually related. He definitely wasn’t just sniffing, you could hear the sucking sounds. Any possible reasons this could be happening? Any chance it may indicate she’s pregnant if she producing milk? She’s big in general width wise since we got her, so I can’t begin to guess whether she’s just a fat mini or potentially pregnant. She’s moody all of the time anyway, so not necessarily any change in her behavior. He’s far from a baby and I’ve never seen this happen with any of our other horses so am quite confused! Backstory: We recently rescued three minis (one stallion, two mares) who had little to no human interaction prior to coming to us. We were just able to put leads on them and have come farther with one mare than the other two. The vet came out several times to check them out and to schedule castration on the stallion, but they were too wild to be able to do anything (according to her). The farrier was not a hit either. We were not given a history as to the relationship of the three (family, mother, etc) and to our knowledge we can’t be certain if she’s been pregnant on the past. There was some speculation that the mare in question may have been the mother to the other mare, but who knows. We have NEVER seen the stallion make any moves on the girls, so wasn’t overly worried about it as we were trying to bond in these early stages. I did think I saw the stallion getting a little frisky with the other mare (younger one), but nothing too egregious.
