It hard and feels like crumpled shell. She leaked some liquid out first and was straining. I saw this coming out of her vent and gently pulled. And then after that came a shell-less egg. She has been sick since Thursday. See https://www.backyardchickens.com/forum/viewtopic.php?id=596430 I have her in a warm tub to try and see if she will push anything else out. What else should I do?
