Leave them! On my hatch I had some pip and wait and some pip and zip pretty fast. A couple of them I was sure wasn't going to hatch(no pip at all), but the next morning there were broken egg shells and babies galore. It's so hard to have babies in there and not be able to cuddle them, just torture!
Hatching is a pretty amazing thing, isn't it?! Congrats on your babies!
My number 3 chick is still stuck in it's shell it hasn't been almost 24 hours. I used a straw to add more water to the incubator to keep the humidity up. Could it have been just too dry?
Should I stay patient and keep the other two chicks in there till it hatches?
