Few things worry a quail keeper like opening the cage to find no eggs. The good news: a sudden drop in laying almost always traces back to one of a handful of fixable causes. Here are the seven most common reasons Coturnix quail stop laying — and exactly how to get your hens back on track. (For the full picture, see our complete care guide.)
1. Not Enough Daylight
This is the number-one reason, especially in fall and winter. Coturnix hens need 14–16 hours of light per day to keep laying. As the days shorten, production naturally winds down — just as it would in the wild. The fix: add an LED bulb or rope light on a timer to reach about 15 hours total. Add the extra light in the morning so birds aren’t suddenly plunged into darkness at night.
2. They’re Molting
Once a year, usually as days shorten, quail drop and regrow their feathers. While molting, their bodies pour nutrients into feathers instead of eggs, so laying pauses for about 4–6 weeks. You’ll see loose feathers and a scruffy look. The fix: there’s no rushing it — raise protein a little to support feather regrowth and let them rest. They’ll resume on their own.
3. Stress or a Recent Change
Quail are sensitive. Moving them, adding new birds, a predator scare, a loud disturbance, or a sudden weather swing can all shut down laying. The fix: most stress-related stops resolve within about a week once things settle. Keep their environment calm, stable, and predator-secure.
4. Diet Is Off
Low protein or calcium stalls production fast. Laying hens need a feed with around 18–20% protein plus free-choice calcium. If you recently switched feed — or you’re using chicken feed instead of game bird feed — that’s a likely culprit. The fix: get them back on a proper layer ration and offer crushed oyster shell. Our feeding guide breaks down exactly what to feed at every stage.
5. Age
Coturnix lay best in their first year. Output tapers in the second year and keeps declining after that. If your hens are past 14–20 months and slowing down, that’s simply age. The fix: rotate in younger hens periodically to keep your overall production steady.
6. Temperature Extremes
Both bitter cold and intense heat suppress laying, and heat stress above about 90°F is especially hard on production. The fix: provide shade and cool water in summer, block drafts and keep things dry in winter, and aim for stable, moderate conditions year-round.
7. Illness or Overcrowding
A sick bird stops laying, and overcrowding causes stress, bullying, and disease that ripples across the whole covey. The fix: watch for sneezing, lethargy, or weight loss; quarantine anything suspicious; and give each bird enough space (at least one square foot in a cage).
Diagnose It Fast by Tracking
The keepers who solve laying problems quickest are the ones keeping records. When you log daily egg counts, you can see exactly when production dropped and line it up with what changed — a cold snap, a feed switch, a move. Quail Keeper Max charts your egg production over time and lets you note health and feed changes alongside it, so the cause usually jumps right out.
