If you want to wait a bit, you can mark the fluff for temporary identification. Blue kote works well, and they will lose it as the lose the fluff. Permanent marker can add some color, and you can mark them in different locations etc. You know that the wings feather in first. This should buy you a couple weeks at least. I have waited one and two weeks, but my batches were hatched and kept separate when I did.
