This probably illustrates my lack of knowledge about mashing in general, but I'm going to brew a barleywine with first runnings, and a stout with the second runnings. I'm going to be adding 1 pound each of Crystal, black, and chocolate malts, and possibly a couple pounds of wheat malt after I have drawn off the wort for the barleywine.

I'm planning on adding the additional water, add the grain, stir, but then I'm lost. On Denny's page describing batch sparging, he says immediately draw off again, but this is without additional grain, for a single beer. How do I do this for two separate beers?

You're thinking correctly. Add the grain, stir, and wait the normal amount of time you would spend to let the grain settle out. Do your normal vorlauf and drain it into the 2nd kettle.

I think you'll need to do some extra work to get the sugars converted in the malted wheat. I don't think you'll need to do that if you used flaked wheat instead, though. The sugars in the crystal, black, and chocolate malts don't need to convert. Between the stirring and vorlauf, you'll get it all mixed together well, just by virtue of the normal processes of batch sparging.

I often do what you're describing when I make a barleywine. As long as the added grains don't need to convert (and in your example they don't) you really don't need to wait at all. At least I don't, and it works fine for me.
