You walk out to the coop in the middle of July, lift the nest box lid, and find it empty again. If you are asking yourself why are my chickens not laying, summer is one of the most common times for it to happen, and heat is usually near the top of the list.
A flock that filled the egg basket in May can slow to a trickle in July, and it is easy to assume something is wrong. Most of the time it is not a disease or a failing flock. It is a handful of very normal summer pressures, and once you know what to look for, most of them are fixable.
Key Takeaways
Do Chickens Stop Laying in Hot Weather?
Yes, and it is one of the most predictable things a flock does. A laying hen’s body runs warm to begin with, around 105 to 107 degrees Fahrenheit, and she has no sweat glands. When the air temperature pushes past roughly 85 degrees, she shifts nearly all her energy toward cooling herself: panting, holding her wings away from her body, and drinking far more than usual. Egg production is metabolically expensive, so it is the first thing her body sets aside when she is heat-stressed.
You will often notice the eggs themselves change before they stop. Shells get thinner and more fragile in hot weather because panting throws off the blood chemistry a hen needs to build strong shells. If you are seeing soft or thin-shelled eggs alongside a lower count, heat is very likely the driver. We go deep on cooling strategies in our guide to heat stress in chickens, and those same fixes are what get eggs back on track.
The Other Summer Reasons Hens Stop Laying
Heat gets the blame first, but it rarely acts alone. Run through this list before you worry.
Molting. Most hens molt in late summer or fall as daylight shortens, dropping feathers and rerouting protein into regrowing them. A molting hen almost always stops laying for a few weeks to a couple of months. Look for feathers scattered around the run and a ragged, patchy appearance.
Broodiness. A broody hen wants to hatch eggs, not lay more. She will flatten herself in the nest box, puff up and growl when you reach under her, and stay put for hours. While she is broody, she will not lay, and she may keep other hens off the nests too.
Dehydration and low feed intake. Hens eat less in the heat, which means less of the protein and calcium that egg-making requires. If their water is warm, dirty, or too far from the shade, they will drink even less. Cool, clean water within easy reach matters more in July than in any other month. It’s important to keep your chickens hydrated in the summer.
Stress and disruption. Predator scares, a dog running the fence line, rehoming, or adding new birds all rattle a flock enough to interrupt laying. If you recently expanded your flock, give the birds time to settle. Our walk-through on how to introduce new chickens to your flock can smooth that transition and cut down on the stress that stalls eggs.
Age. Hens lay best in their first two to three years, then production tapers. An older flock naturally lays fewer eggs, and heat exaggerates the drop.
Are They Actually Not Laying, or Hiding the Eggs?
Before you troubleshoot a health problem, rule out the simplest explanation: your hens may be laying somewhere you are not looking. Free-ranging birds in particular love to tuck a clutch under a shrub, behind the feed bins, or in tall summer grass. A hidden nest can hide a dozen eggs before you notice.
Keep hens confined to the run until midmorning for a few days so they lay in the nest boxes, then watch where they head when you let them out. Walk the fence lines and check the shady, sheltered corners of the yard. More than one homesteader has solved a laying mystery by finding a pile of eggs behind the woodpile. It is worth ten minutes of searching before you change anything else.
How to Get Chickens Laying Again in Summer
Once you have identified the cause, the fixes are straightforward and most of them help across the board.
Start with water and shade, because they solve the biggest problem. Give the flock cool, clean water in more than one spot, refresh it during the day, and drop in a frozen water bottle or some ice on the worst afternoons. Make sure there is real shade over the run, whether from trees, a tarp, or a simple DIY shade structure you can throw together in an afternoon.
Next, protect their protein and calcium. Feed a complete layer ration and resist the urge to overload on watermelon and scratch, which are fun treats but dilute the nutrition a laying hen needs. Keep crushed oyster shell available free-choice so hens can top up the calcium that thin summer shells are telling you they lack. Feeding during the cooler morning and evening hours encourages hens to eat more overall.

Finally, lower the stress. Keep the routine steady, secure the run against the neighborhood dog or the midday hawk, and give any new or recovering birds a calm environment. If a hen is broody and you do not want chicks, gently remove her from the nest several times a day, or set her in a wire-bottomed cage in the shade for a few days to break the cycle.
For most healthy flocks, a summer slump is temporary. Cool them down, keep the good feed and fresh water coming, and once the fiercest heat breaks and the molt finishes, your hens will find their rhythm again. The reputable poultry team at Extension’s poultry resource is a solid place to dig deeper if a slump drags on well past the hot weeks, since a long, unexplained drop can occasionally point to parasites or illness worth a closer look. A protein boost can help, and some keepers cover that by raising mealworms at home.
Frequently Asked Questions About Why Chickens Stop Laying
Why did my chickens suddenly stop laying in summer?
The most common reason is heat. Once temperatures pass about 85 degrees Fahrenheit, hens put their energy into staying cool instead of making eggs, and you may see thin shells before production drops. Molting, broodiness, dehydration, and stress can all pile on at the same time.
At what temperature do chickens stop laying eggs?
There is no single cutoff, but laying commonly slows once daytime temperatures climb past 85 to 90 degrees Fahrenheit, and the effect worsens as it gets hotter. Providing shade, cool water, and airflow helps hens keep laying through a heat wave.
How can I get my chickens to lay again?
Focus on cool clean water in multiple spots, real shade, a complete layer feed with free-choice oyster shell, and a low-stress environment. Feed during the cooler parts of the day so hens eat enough protein and calcium. Most healthy hens resume laying once the heat eases.
Could my chickens be laying somewhere I can’t see?
Absolutely. Free-ranging hens often hide clutches under shrubs, behind buildings, or in tall grass. Keep the flock in the run until midmorning for a few days to encourage nest-box laying, then search shady, sheltered corners of the yard.
Do chickens stop laying when they molt?
Yes. Molting hens redirect protein into growing new feathers and almost always pause laying for a few weeks to a couple of months. A patchy, feather-strewn run in late summer is the telltale sign.
