I’ve seen mistakes in books or movies regarding hatching eggs, be it chickens or dinosaurs, so I decided to set the record straight.
Here is the normal hatch sequence:
If you’re writing a book and someone is hatching an egg, it’s important to let it hatch on its own, not break it out like some books or movies do. Breaking it out too soon means it may not be ready to come out, which can cause bleeding, among other things like a yolk sack hanging out, which is normally fatal. Once they’ve started circling the egg, like in the second picture, helping generally won’t cause too much trouble since they’re about ready to come out.
Another common mistake is animals that pop out of the egg and are fluffy and running around. When a chick escapes the egg, it’s pretty tired and can’t walk. It also won’t hatch out of the egg all fluffy. It will be a wet mess.
I’ve had a few complications with hatching eggs. One issue is when the chick is backwards, meaning it’s hatching from the small end of the egg instead of the big end. This normally goes okay, though it’s not a bad idea to keep a close eye on eggs that are backwards. I had one chick finish the circle and get its head out of the egg, but the hole was too small for the rest of the body so I had to help it.
If anyone has egg related questions, I’ll be happy to answer them.
