I put 20 viable eggs on lock down on day 23, yesterday 16 out of 20 hatched!! Of the four left, one has pipped all around and has been working at hatching since yesterday afternoon, I don't see movement this am though. The other three don't look pipped yet. My question is, will I risk the four left if I take the 16 out of the brooder? If it is safe to open the inci, should I try to help the one pipped? And if I should not open the inci until they are all done, how long do I wait until I give up???? Thanks!
