My hen Vivian, born on March 18th, laid her first egg on August 6th. She laid almost daily up until September 28th, and hasn't laid since. Her "sister" Esmerelda (who is the same age) started laying on August 23rd and has been laying eggs consistently, pretty much every other day or a little more often, and hasn't stopped. Since Esmerelda hasn't stopped laying, I was wondering if it was normal for Vivian to stop, and when I can expect her to start again? I am just getting a little nervous and want to make sure there isn't anything wrong with her.
