It's the third segment in the show, and Bill Nack narrates. Very sweet piece. It doesn't talk about her life post-career, but if I remember right from the updates, she's been adopted by a veterinarian who works with the farm where she trained who just fell in love with her, and is (I think) being trained for fox hunting, which should be fun for the wee girl.
As for the other two, who are just briefly mentioned, the other filly has been bred, and the gelding, who suffers from water on the brain, possibly due to being denied water when he was little, will be cared for as long as he is physically comfortable. If he ever looks to be suffering, they'll perhaps make the choice to euthanize him, but for now he's living with a herd of horses and very fond of physical affection.
Not a bad ending for three little runts left to starve. Take that, PETA! (That last one is for IC's benefit.

)
