I had a first. Chick pipped the wrong end, then tried to zip the length of the egg and got stuck. It'd had a huge pip hole for 4 or 5 hours and the fluff sticking out was dry so time to step in. Just stuck to the membrane around the big hole by a wing, not fully shrink wrapped. I was really confused when looking for the head until I realized how it was trying to zip.
Nice perfect little feet. I always look at toes. Had to press it's feet flat after peeling it out. I found that helps prevent toe problems if you emulate how they use their feet to push out.
This was the egg I didn't think would hatch.
