[JasmineFlow2012]

Hi

How do i retire a horse?
how old do they have to be of their age points before i can send them to the nursing stable?
How do i put them into the nursing stable? - does this become an option once they re old enough?

You can't "retire" a horse, it happens only when they reach a certain age. For starter horses, that age is 20, and increases as your breed mastery increases.
Horses are automatically moved to the nursing stable once they retire (you don't have to put them there). If you don't have enough stables in the nursing stable, they show up as an empty box in the regular stable.
