I am sorry to tell you may wait till spring now
Certainly a possibility. We did only just get that first white egg at 36 weeks old. The other 2 not laying are the same breed/same age as that one. We added light to the coop 2-3 weeks ago (for approx 15 hours of light a day) and saw an increase in egg production as the other layers had been decreasing their egg laying a bit. But, we have heritage breeds, so would never expect 1/day from each. It’s to the point of just sheer curiosity as to when the other two will lay their first egg!
