One of my chicks pipped on the wrong end around 5am this morning. He's been chirping and the egg has been moving ever since. He managed to get the tip of his beak through and nothing else. It looked like his beak was upside down and he never managed to shift positions. So I peeled back some of the shell (leaving the membrane intact). It seems his head is curled around backwards in the small end of the egg. I tried peeling back more of the shell so that maybe he'd have the room to turn around, but he is still in the membrane with his head curled backwards, chirping his head off. I'm starting to think I may have to help with the membrane I've never done this before. Any tips or important info?
