It seems to take my Easter Eggers about 26 hours to lay, so if they lay one at 8am, then tomorrow's won't be 'til 10am, then the next day at noon, next at 2pm, etc., and then they'll go a day without laying, then back to 8am again.
The RIRs, Doms and Black Australorps lay every day, but the time of day swings early (sometimes even at the crack of dawn), then later, sometimes as late as dusk (rare, but happens). With 11 hens, I get eggs starting as early as 8am, all the way 'til at least 6pm, sometimes even later.
Silly chickens!
