I know we're not supposed to help, but one of my chicks got stuck in his egg. Pipped on day 17, zipped sometime, but on day 18 it was completely still. Day 19 I thought, what the heck, let's see why it died, and picked it up and gently pulled the two halves apart (egg was very hard and crackly dry.) I put it down and almost immediately, the chick popped out! It had completely curled feet, but a day of painter's tape snow shoes fixed that. He was very runty for a while, got a lot of holding time in, and now isn't even the smallest of my chicks (3+ weeks old) and seems to love being held. Pick him up and he goes limp, closes his eyes, and makes crickety noises. So, yeah. I know we're not supposed to help, but maybe sometimes we should.
