Welcome to BYC. Glad you decided to join our flock. If your hens are not laying, there are several that need to be asked. First are your hens molting? Molting hens will not lay until after they finish their molt. Second, are they broody. Broody hens will not lay. Third, do they have plenty of light for at least several hours per day? Light striking a hen's pineal gland is what stimulates her to lay. Fourth, has anything happened recently to stress your hens (predators in the area, barking dogs, a move from one location to another, too many roosters in your flock over-breeding your hens, etc.)? Hens under stress will stop laying. Fifth, are your hens being free ranged? If so, they could be laying somewhere else besides the nesting boxes. Sixth, are your hens in good health? Poor health caused by illness, mite or lice infestations, etc. can cause your hens to stop laying. Sixth, how old are your hens? Old age can certainly bring their laying to an end. Please feel free to ask any questions you may have. We are here to help in any way we can. Cheers.
