Hazel's stomach has been hurting, then all the sudden she realizes she has laid an egg. She is so confused and doesn't know what to do besides maybe try and hatch it in case there is a little chicken or some creature in there. She makes a little nest and to make the egg feel more at home, she starts clucking like a chicken. I guess either her sitting on the egg or the clucking works because she starts to feel the egg wiggle and its hatching!
