I was wondering if anyone knows why a hen lays--especially for the first time--a wrinkled hard egg?? I have read of different possibilities but would like some more opinions from people who have experienced this more than just 1 time. My hen is a standards barred rock hen and has been laying normal eggs up until yesterday. Yesterday she was acting not her usual self. She didn't lay her egg as always which is between 11isham- 1ishpm. And when she did lay her egg--which was around 6ish--she didn't do it in her nest box but rather the ground outside her coup. I have another chicken but she's just a pullet about to start laying and was wondering if she has to do anything with it. Or if it had to do with my neighbor's dog that scared her. That dog has never been around them till yesterday. Please help!!
