We have 28 hens, some are older 2 years, but some are just 6-8 months. We were getting 9 eggs a day and now have gone to ZERO. With the occasional egg found in the goat trough. They are not hiding, they are just not laying. We stripped down the chicken coop and added new shavings on the floor. Took the hay out of the nesting boxes and added shavings, thinking they may prefer that. Nothing! We have 13 nesting boxes. We do allow the chickens out to free range from about 8AM til they go to bed around 5. We have searched the farm and they are not hiding eggs. Any ideas? I have egg customers and no eggs!
