Anything is possible...I have 3 RIRs and they lay quite consistantly. The only time I get 5 eggs a day is when my dear boy doesn't collect the eggs after school like he's supposed to!
Biologically, chickens lay an egg evey 26 hours. They ovulate only during daylight hours, thus every week they will appear to "skip" a day as their body resets. That is why in the winter, chickens tend to lay less often - shorter days.
