Many of you probably already know this, but I found it fascinating. The oldest horse ever recorded was Old Billy, a black horse with a blaze who was believed to be a cob/shire mixture. He was a barge horse born in 1760, who died in 1822. As far as I know the oldest currently living horse is a 51 year old morgan named Copper, but I don't know how many years ago that was established. I think a few now. So if he is still alive, he is even older! What is the oldest horse you have ever had/seen? Why can't we get more of our horses to live so long! Lol. What I originally saw (which lands this in the breeding section), is the oldest known mare to give birth was a 42 year old Australian broodmare. Don't know how substantiated this fact is. The longest tail ever recorded was 22 FEET LONG! It belonged to a palomino named Chinook. Totally non-horse related, but the world's oldest woman to give birth was 72, she had twins in July of 2008. EEK! The dad was 75! Talk about potent. Lol.
