Yes, I've read that too but it's SOOO worrying. I'm pretty sure I haven't got the humidity high enough in the incubator although I have followed instructions the reading is still low.
So I'm really worried that the shells aren't going to be soft enough for them to get through.
My goodness this is hard work :roll:
And yes I know it's even harder for the little chickies! They do seem to be stimulated by us talking to them or cheeping at them (even my anti-chicken OH is cheeping at them!
).
