It doesn't have to be bright and sunny to trigger laying - even with our usually overcast days I have 1 bird that's started up again (honestly wasn't expecting it, but glad to have it). As the daylight hours lengthen I think you'll start getting closer to getting eggs, and not sure if gradually increasing artificial lighting to 12-14 hrs at this point is going to get you there any sooner. But no reason not to try it either.Yeah could be, we still have 2 months of pretty dark days, just sucks getting no eggs for like 5 months.
Do you know how much would be worth it? Right now they get maybe 8 hours of daylight (really though it’s way less because that’s the sunset/rise hours but there’s been no sun for weeks just dark cloudy. One sunny day in a month.
if I add 4 hours so it’s 12 hours is that worth it? or just wait until next year to do it?
Best way to get eggs through winter, as aart noted, is to add new chicks every year. That may require cycling out older layers (2+ years) but not sure how you feel about that. Or if you don't want to grow the flock that quickly, my way of handling it is we start slowing down egg usage in August or Sept, and I start hoarding eggs from then on. I'm still sitting on the last dozen or so from last year, so haven't had to buy eggs yet.
