Laying pattern changed...is this normal?

[my first peepers]

My first pullet to start laying was sometime in mid-late October. She pretty quickly established a pattern of laying for three days then skipping a day. Recently she started laying only every other day. Is is normal for a young layer to change their pattern like this or is there something I should be concerned about?
I haven't noticed anything visibly wrong with her.

Normal, could have somthing to due with the winter and shorter days also !!

I think hens really do lay in clutches. The broody types can get the production turned off and go ahead and set. The more productive types just kind of stutter a little and start off on another series of eggs.

And yes, the short days interfere with the cycle of production. So does the stress of cold weather and the other of life's vicissitudes . . . (nearly drop my dentures every time I try to pronounce that word

.)
