Chickens stop laying eggs for a variety of reasons. Hens may lay fewer eggs due to light, stress, poor nutrition, molt or age. Some of these reasons are natural responses, while others can be fixed with simple changes and egg laying can return to normal.
If you’re a backyard chicken raiser, you’ve become accustomed to your morning routine: Wake up. Drink coffee. Collect farm fresh eggs from your backyard flock. As the days become shorter and temperatures drop, you may notice fewer eggs when you go out to the chicken coop. It may have you wondering, “Why won’t my chickens lay eggs?”
Some of these reasons are natural while others can be fixed with simple changes. It’s up to us as flock raisers to solve the mystery of why farm fresh eggs might be missing from the nesting box.
The first and most common cause of decreased egg production is light hours. Hens need a minimum of 16 hours of daylight to sustain strong production. Without supplemental light, they may naturally stop laying eggs due to a hormonal response as the days get shorter.
Hens lay best when provided at least 16 hours of day light, whether natural, artificial or a combination of the two. Some flock raisers use winter as a period of rest for their hens without supplemental light.
If you’re looking for consistent egg production through the winter months, provide additional light to encourage your birds to keep laying.
We recommend using one incandescent 25-watt or LED 3- to 9-watt bulb per 100 square feet of coop space. If supplementing with artificial daylight, keep your flock’s exposure and sleeping schedule consistent by putting lights on timers.
Another reason for decreased egg production is over-treating and over-supplementing hens. Added treats and scraps can dilute the nutrients in a complete layer feed so the hen is less able to produce eggs consistently.
Laying hens need 38 nutrients for consistent health and performance. Calcium is the most critical for laying hens; she must consume four grams of calcium each day. Complete layer feeds are formulated to provide everything hens need in the correct amounts, but if we provide too many treats, then those nutrients become diluted.
A general rule to follow is the 90/10 rule. This means the hen’s diet should be made of at least 90 percent complete feed.
Around 18 months of age and annually after, chickens go through molt, which is defined as a period of feather loss and regrowth. Molt usually occurs in autumn and is associated with a decrease in egg production.
Molting chickens redirect their energy from laying eggs to growing feathers. This results in a brief break from egg production. Molt typically lasts eight to 16 weeks, depending on the bird. Once she has a new set of feathers, egg production should return to normal.
To help hens through molt and return to laying eggs, switch to a high protein feed during molt, like Purina® Flock Raiser. Once egg laying resumes, transition back to a layer feed higher in calcium, such as Purina® Layena®, Purina® Layena® Plus Omega-3, or Purina® Organic Layer Pellets or Crumbles. All these feeds can be Purchased at Burns Feed Store.
