The hen in question is 11 months old. She was laying regularly up until a few weeks ago when the soft shelled eggs started. She is acting normally now, and I do see her at the feeder quite often. However, she has not layed an egg (soft shelled or otherwise) for over a week now.
Well hopefully it's just a glitch in the system. While she's not a "new" layer she's still on the young side so sometimes their system does odd things while trying to get all the kinks to laying out. I have a pullet that was laying poopy eggs everywhere except the nest box, then stopped completely for a while, and is now about 11 mos and only just started laying again (inconsistently, but in the box). Don't know why she stopped or why she was having pooping on eggs but seems she's finally sorting it out.
