There are WAY too many eggs for those two girls to keep warm, probably close to 30 of them. Most of them on the outside are probably not viable. The ones in the middle are likely to be the only ones that developed. I'll go candle them later tonight to see how many to toss.
I may have been wrong about how many eggs have a chance. I just went back out to peek at them and I couldn't see a single egg. The hens had them all tucked out of sight. I only saw one baby while I was out there too. Poor thing was having a hard time squeezing under the mamas with all those eggs.I read they rotate them to the center... which can mess them all up
