I've been pumping the soft egg shell hen full of calcium all week, she was laying one egg a day then nothing for four days. Also have an EE that is an every other day girl, but this is her 2nd time with no egg. Even though it's been kinda gloomy they've been spending their days outside, usually sun up to sun down.
Probably just the light and days getting shorter. They'll sometimes "take a break," especially if they've been really consistent layers.
