My Blue Wheaten Ameraucana couldn't exit a nestbox fast enough after laying her eggs and sometimes her klutzy feet/toenails would make a hairline crack in her just-layed egg as she made a hasty exit. Happened about 3x when we had her. Another time she was so anxious to leave the nestbox she knocked a Silkie to the ground who was sitting on the nestbox ledge and I had to take the Silkie to the vet. Don't know what makes these incredibly gentle Amer's so hyper, jittery, and jumpy. She trusted us and let us pet her, hold her, feed her treats but she was simultaneously alert/aware of noises or motions going on around her at all times.My one Easter Egger lays massive eggs when she first started laying. Now she's recently gone back to more normal size eggs but they're still pretty big and occasionally she still throws a huge egg. Usually she then takes a break for a day then resumes laying. She laid big eggs from her second egg on (first was broken shell). Hers were also often double yolkers. So i hope she doesn't become egg bound eventually.
TYPoor hen and you! So sorry, had no idea
