Okay, I called back at the ranch, because I was confused too. The owner of the ranch - Leonard - wasn't the one that called me. It was one of the newer ranch hands that thought she was 43. [I didn't think that was right either, and as I thought about it after posting this, I knew it wasn't right.] She was actually 25, and the foal is at the age that he CAN eat by himself. He's buddied up with one of the other stallions, so I'm assuming they're going to be pals for ages.
And, yeah, I didn't particularly enjoy that picture on my phone. He's not the most tactful of people when it comes to stuff like that. A little green around the edges.
I personally didn't have anything to do with finding her or burying her. I just use "we" as a general term, 'cause we're kind of like a family out there. I wonder if I can edit posts after I've posted them.. Sorry for the confusion!
