Oh, OK, that makes sense. This mare was very very old and IMO, pretty run down. She had sent the pair over to breed her back when the baby was just, maybe, a week old. I had to call her twice and say this foal is lame. She took them home. I did take our stud over to her place to breed her mare, but was very glad she never got in foal again. I didn't think the mare should be breed, but had agreed to it before I saw the condition of the mare. She'd breed this mare every year for years. I think it was just the next year she had to put her down because she foundered.

She's probably fortunate she didn't have another foal off that mare, it doesn't sound like her health was any good to start with. Getting a healthy foal with a young healthy mare is never assured, starting with less than that is asking for heartbreak.
