I have 15 minis, down now from 30 head I had a few years ago. 6 stallions, 1 gelding, 8 mares.
My oldest is a 35 year old mare I bought when she was 4 yrs, all the rest are horses that I bred and were born here.
3 mares are 24 yrs, one 26 yrs, one 27 yrs, one 22 yrs and one 19 yrs
6 stallions are one 31 yrs, the one in my avatar(Max) one 23 yrs, two are 22 yrs, one 21 yrs, one 16 yrs.
several are former show horses, halter and driving.
needless to say, I stopped breeding 15 years ago.
