They’re supposed to have their head tucked under their wing, probably just shifted as it was chewing etc. Did it take that shell off or did you?

as long as it can breathe it’s ok. Sometimes when they’re ready but can’t quite arrange themselves properly, they start flailing and screaming, so if it’s quietly sitting there chewing and yawning, it probably still just needs more time. If you’re going to start investigating, the best thing to do is to make a hole in the air cell end to see what’s going on with the veins and things. Some people bring the egg into the bathroom with the shower running to keep the humidity up. (Don’t bring the egg into the shower itself, but having it running makes the humidity jump in the room. Lol). I don’t usually and haven’t had any issues, but if you’re concerned about the humidity, that’s one way you can keep it up outside of the incubator. Follow the assisted hatching guide, make a hole in the air cell end carefully, moisten the membrane and check for active vessels or if you can see yolk still. If you want to take a pic of it and share it, that’s fine too. Always start any assistance from the air cell, even though it’s pipped the wrong end.
