Aloha, and welcome to BYC. Glad you decided to join our flock. Which area of Hawaii are you in? My family and I live in Hawaii for 23 years, first on the big island and then on Oahu. Molting will definitely affect their laying as hens stop laying while they are molting. If that is the cause of their not laying, they should begin laying again when they finish molting. Other things that can cause hens to stop laying are broodiness, lack of sufficient light as light striking their pineal gland stimulates them to lay, stress (from predators in the area, barking dogs, a move from one location to another, too many roosters in your flock over-breeding your hens, etc.), poor health caused by illness, mite or lice infestations, and old age, etc. can cause your hens to stop laying. Also if your hens are being free ranged, they could be laying somewhere else besides their nesting boxes. Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck wi da' flock.
