Some breeds don't lay often and molting, and short daylight hours will slow chickens down also.
I had real good egg production the first 2 years, but this third year is nothing to talk about. I guess that is why so many people around here turn over their flocks every 2 years. And yes, some of my chickens are in molt and our days are getting shorter and shorter. Everything working against the girls at this time in terms of egg laying, but they all appear to be happy and healthy.
