Thanks for this discussion. I'm reading this on day 20 of my first attempt at hatching. Of 37 eggs in the bator, 3 chicks are completely out of the shells, and another 10 eggs pipped. I have been worrying about everything. My teenagers were convinced I should have opened it up to 'save' a chick who couldn't get his head free from the last bit of shell. He's free now of course, with no intervention. I came here trying to find a reason to open the lid and 'help' - thanks again for the firm 'No!'
