I've posted my cider method in homebrewopedia under common cider - Delmarva Cider, if you want to look it up. Unless you've heated it, which you shouldn't, cider is well aerated already. Boiling drives oxygen out of beer wort. And I've nix nutrients. All they'll do is help the yeast eat up those last few bits of sugar and bone dry cider doesn't taste like much. Ferment cold if you can. It will be better.
And I see euge and I have given you opposite answers ... That's the internet for you.
