My husband and I just inherited 22 acres of farmland that just so happens to come with a 35 year old mini mare and a 4-5 year old mini jack (his gelding is scheduled for May 20)! We also picked up our ‘miniature’ Curly filly and celebrated her first birthday! Yay! The little 35 yo mare is really small IMO, but seems healthy. When the vet comes out to geld the jack, I’m going to have her look at the mare too. Anyway, she’s just out on grass with the jack and seems to be doing ok. I just know that age has it’s negative effects on their teeth & digestion. She’s quite the firecracker...the jack *really* wants to make happy with her & she gives him 2 hooves of ‘No’! We plan on introducing the filly to the old mare and gelded jack in the near future (after all his swimmers are gone). I’ve never had a horse this old before...my oldest horse was 28 and he was injured by my then 2 year old QH filly before he had to be put down. I don’t want to risk injuring the mare, but I would like to be able to put the littles all together and away from the ‘bigs’ (our biggest is 13-2HH) to prevent injuries. I’m thinking if the old mare can keep the frisky jack off her back, our fairly tame, but larger, filly shouldn’t be too much of an issue. I think the filly will mature between 38-40”. If I had to guess I’d say the old mare is between 34-35” (the jack is about the same height). What would you guys recommend? The photo of me sitting on the ground is with the filly. The other is me with the jack with his old mare friend looking on. For reference I’m 5’6” and from the ground to my hip bone is about 36”. The last one is just me showing off my little filly’s good nature! BTW the old mare’s name is Molly the Pony (said similarly to My Little Pony). The jack’s name is Dave (the donkey). The filly is Annie Get Your Gun or Annie Oakley.
