My girls are laying steadily, which is excellent. This afternoon I went out after the last one was out of the nest box and collected three eggs--one per chicken. Just a little while ago, I let them out to wander the yard for a while. I was watching my blue wyandotte and easter egger battle over a night crawler (advantage wyandotte) and then the wyandotte sort of froze in a half-squat. She looked a little concerned, so I bent down to see what was up, and realized she had just laid a soft-shell egg. She looked pretty surprised, and I know I was! A few minutes later she was off running and scratching again. She seems totally fine, so I'm not exactly worried, but I was certainly surprised, since she just laid this morning! Have other people had this experience? They have plenty of oyster shell right now, so my thought was that this egg just got hurried along inside her for some reason and didn't have a chance to fully develop its shell. For what it's worth, they all started laying just a few months ago, so while they're pretty regular, maybe they're still working the kinks out of the system.
