Great hatch!!! We are full blue too, for the reasons you have stated. Congrats on the high numbers!Final update on my hatch last week. 12 hatched out of 14 good eggs. One did expire already. It pipped externally and then dried out so we helped it out. It had curled feet. It died a day later. So we have 11 new chicks on the ground. I need to get a good pic of the group. 6 yellow, 5 Marans chick color (one died) and 1 grey chick patterned like a Marans. Interesting. And a few of them have feathered shanks.
Of the eggs left I did candle them and one had internally pipped. Sad too, you could see the scratches on the inside of the egg where it failed to pip externally. I'm just not going to look or help anymore. I'm going full blue from now on. It sucks to have the kids see the curled footed chicks scream and then finally die.
I think the two had issues from the temp drops.
