I have a few thousand eggs i got on wednesday that were suppose to have a cold pack so I could refrigerate, but there was a mix up and they didnt come with one, so I had to hatch out all of them, well, they are already starting to hatch, but only about 100 out of the 3500 have hatched how long do I wait to feed and what do I do with the hatched ones, they are too small to seperate, thanks.
