Sudden spike in egg laying within the past 2 days

[KikiDeAnime]

We've been having terrible weather and really cold temperatures here for a week or two and the egg production dropped to 2-3 eggs a day. The past 2 days we've been getting 5-6 eggs a day despite the weather. And our 2 bantam polish finally decided to start laying as well. So now we have a full 18 carton plus 4 eggs. We already had a dozen in the carton so this added onto what we have.

What's with the sudden spike in egg laying?

What's with the sudden spike in egg laying?

12.5 hours of daylight. Sunrise 6:39/Sunset 7:12 here.
I find when available light drops under 12.5 hours so does laying.
Just the opposite in the spring when available light goes above 12.5. GC
ETA; I add light at 5am so egg laying went up here a month ago.

More daylight! Spring is here!!!!
I was getting an average of 2 or 3 eggs a day over winter. Now I get between 13 and 15 each day!
