Why aren’t my 2 ½ year old speckled sussex chickens not laying?

[clickncluck]

My 3 speckled sussex chickens haven’t laid an egg since mid September. They had a mild molt in September but have long since grown their feathers back. I wormed them in October. Supported them nutritionally with extra protein during the molt. I feed them Purina organic l’arena pellets. They have additional cups of grit and oyster shell available. I live in Hawaii where the length of the day is never longer than Are they just done laying? Is this typical of Speckled Sussex? Any ideas?
Thanks

At 2 and a half years old they are long overdue for a break in the laying cycle. They will lay again only not as prolifically as before.

Days aren’t ever longer than 13 hours 26 minutes.

Maybe @Pork Pie can help, he's closer to the equator than most of us here.

You no longer have birds....or you regularly cull birds to keep fresh layers??
