My hens usually (always) lay their eggs in the nest boxes. Yesterday I found this little "thing" that looked like an egg in their run. I took a picture of it compared to one of their regular sized eggs. At first I wasn't even sure it was an egg. But I cracked it open and it is an egg. Anyone have any insights as to what this is all about. My 4 hens are about 9 months old and have all been laying pretty regularly. Thanks for the help and insights.
