Why do hens stop laying? Here are some reasons why your hens may not be producing eggs.
Many things can cause hens to stop laying eggs, but the primary reason is decreasing day length. Hens need a minimum of 17 hours of daylight to sustain strong production. If you don’t provide your hens with supplemental light, they will naturally stop laying eggs when daylight drops below 12 hours per day. Hens may also stop laying if light abruptly decreases by a few hours. This is a hormonal response regulated by a tiny gland that responds to changes in light. One 40-watt bulb per 100 square feet of coop space is enough to keep birds laying. Use an automatic timer to keep light and dark hours constant; just a day or two of too little light can end a laying cycle.
Inadequate nutrition is another reason hens stop laying and, surprisingly, the missing nutrient is often water. Hens need a constant source
of fresh water, and they do not like it very cold, so it is important to check and refresh waterers often in the winter. Cool water in the summer will help the birds combat the effects of heat. Never underestimate the importance or power of clean water at the right temperature!
Inadequate protein and/or energy can cause a production decrease. A shortage of dietary calcium will result in weaker eggshells and, eventually, weak bones as the hen robs her skeleton of calcium in an attempt to manufacture shells. Feeding too much “extra” feed, such as scratch grains or table scraps, can dilute and unbalance the complete nutrition in the hen‘s pellets or crumbles, thereby affecting her production and health. Hot weather will inhibit a hen‘s appetite, causing her to eat less and resulting in a drop in egg production on even the best diets. Offer a high-quality feed and severely limit table scraps and alternative feeds to obtain maximal egg production.
Diseases and parasites will reduce a hen‘s productivity as well as her comfort. Build a relationship with a veterinarian who can help you establish a good flock health program. Never introduce new adult birds into your flock — apparently healthy adult birds can be carriers of a number of deadly diseases. Keep all premises as dry as possible to limit growth of coccidia, an insidious and stubborn parasite that flourishes in dampness causing coccidiosis.
Egg production decreases with increasing age. Good hens will productively complete two egg-laying cycles of 50 to 60 weeks each. After that, production will drop off greatly.
Any kind of stress — extreme temperatures, excessive handling or moving, fright caused by predators, or noisy children (they’re all the same to a hen!) — will negatively affect egg production. Keep your hens’ environment as serene and comfortable as possible to help maintain health and productivity.
Sometimes what appears to be a reduction in egg production is really the result of free-range hens hiding their eggs. Be sure you have enough nesting sites for the number of hens you are keeping, especially if you are allowing some to be “broody.” Make sure the nesting area is warm, comfortable, dimly lit and well-bedded with clean litter. Give the hens lots of good reasons to lay their eggs where you want them.
