milk separated after heating... is the yogurt bad?

[Guest guest]

I made a batch of yogurt from 6 quarts of goat milk. I heated 2 quarts

in one pot and 4 quarts in another pot. The contents of the smaller

pot were heated to just above 180 and then sat for maybe 15 minutes.

When I looked at the milk, it had separated and had tiny curds

floating in it. It didn't smell sour. This has never happened to me

before, and I've been making yogurt every week for over 20 months. The

milk heated in the other pot was fine, and all of the milk was

purchased at the same time. Because I was making the rest of the batch

anyway, I went ahead and added starter to the curdled milk, and

cultured it in a separate container. It's in the fridge right now, but

the resulting yogurt looks like it's in layers - a layer of thick

yogurt on the bottom with a layer of water of hydrolysis on top.

Do I need to assume that this yogurt is bad?

Thanks!
