Chick are pretty resilient if they have a heat source, mine didn't want heat after 1 day in warm weather and 3 -5 days in cold temps of winter here.
on egg that had blood, is it continuing to bleed or was it just a small speck you could see?
For the ones that got pecked, put coconut oil on the membrane to keep it from drying out or lightly wet a paper towel with warm water, making sure it's not dripping and wrap egg and put back in the incubator
Congrats on the ones that are out and gl on the ones still working on it.
