2 hatched... but what about the others?

my broody is sitting on 3 eggs, 3 hatched yesterday, 2 lived. I went to the store to get chick starter, and came back, and she was sitting on the 2 chicks OFF the nest... I don't know if the eggs got cold, but I popped the chicks back into the nest, and she went too... but I don't see any pips or anything. Is there any easy way to tell if those 3 are going to hatch? If not, its 2 out of 12... not a great hatch rate...

 

I tried taking the chicks away, but she wouldn't sit on the eggs... so I took the eggs and put them under our other broody. I don't think they're alive now though.... I've got 3 broodies right now. One sitting on 2 babies, and one sitting on the 3 dud eggs (I know one is dead... pipped, but nothing....) due yesterday, and 8 live eggs due next week, and my last broody is setting on a half/pint jar. I don't think it'll hatch.

anyway, the 2 babies are super cute. I'm going to call the farmer right now and ask what he thinks the gray one could be.

 

he said it's a white cochin, and that some baby white cochins are gray... anyone?
