Laying quail need a high-protein diet with plenty of calcium to produce eggs consistently. A commercial game bird layer feed with 18 to 20% protein is the foundation, but the details of supplementation, portion size, and what to avoid make a real difference in how many eggs you collect and how strong those shells are.
Protein: The Most Important Number
Protein drives egg production more than any other nutrient. Laying quail need 18 to 20% crude protein in their diet. The National Research Council recommends 20% for laying quail, though production can hold steady with as low as 16% protein. In practice, most quail keepers aim for 20% because it also supports better egg quality and nutrient absorption, especially during warmer months when birds eat slightly less.
A commercial game bird layer feed or turkey starter/grower crumble in the 20% protein range is the easiest way to hit this target. Chicken layer feed typically runs around 16%, which is on the low end for quail. If that’s all you have access to, you can boost protein by mixing in small amounts of dried mealworms, black soldier fly larvae, or crushed cooked eggs. But a purpose-made game bird feed is simpler and more balanced.
Crumbles work better than pellets for quail. Their small beaks struggle with standard-size pellets, leading to wasted feed and uneven nutrition. If you can only find pellets, crushing them lightly before offering makes a noticeable difference.
Calcium and Shell Quality
Quail laying daily need significantly more calcium than non-laying birds. Research on Japanese quail found that the best egg production, egg mass, and feed efficiency came from diets containing about 2.7% calcium paired with roughly 0.4% available phosphorus. That ratio matters because calcium and phosphorus compete for absorption. Too much of one limits the other.
Most game bird layer feeds include calcium in the formula, but many keepers supplement further with crushed oyster shell offered in a separate shallow dish. This lets each bird self-regulate her calcium intake based on what her body needs. Oyster shell grit should be finely crushed for quail since their beaks and digestive tracts are much smaller than a chicken’s. Look for products labeled as soluble or digestible grit, which dissolve in the stomach and release calcium directly into the bloodstream.
You’ll also want to offer insoluble grit (tiny granite pieces) in a separate dish. This type doesn’t dissolve. Instead, it sits in the gizzard and helps grind food, improving how well your birds digest and absorb everything they eat. A shallow bowl wide enough for a quail to stand in works well for both grit types.
How Much to Feed Per Bird
An adult Coturnix quail eats roughly 15 to 17 grams of feed per day, which works out to just over half an ounce. That’s not much, so feed quality counts more than quantity. Offering feed free-choice in a small trough or gravity feeder lets birds eat throughout the day, which matches their natural grazing pattern and supports steady egg production.
If you notice feed sitting uneaten and getting stale or damp, scale back slightly and refresh more frequently. Moldy or wet feed is a common cause of digestive problems in quail. In hot weather, birds may eat a bit less, which is one more reason to keep protein levels at the higher end of the range.
Treats and Fresh Foods That Help
Small amounts of fresh food add variety and micronutrients, but they should never replace more than about 10% of the total diet. Good options include finely chopped leafy greens like romaine, kale, or spinach, along with small pieces of cucumber, broccoli, or grated carrot. These provide vitamins A and K, which support reproductive health and immune function.
Live insects are a favorite and a genuine protein boost. Mealworms, small crickets, and black soldier fly larvae all work well. Offering a small handful per bird a few times a week mimics what quail would forage in the wild and keeps them active and engaged. Cooked, crushed eggshells are another useful supplement, recycling calcium back to your flock. Just bake the shells at a low temperature first to sanitize them, then crush finely.
Foods to Avoid
Several common foods are toxic to quail and other birds. Avocado is one of the most dangerous, potentially causing breathing difficulty, heart problems, and agitation. Onions and garlic can damage red blood cells. Rhubarb leaves contain high levels of oxalic acid. All four should be completely off the menu.
Other plants to keep away from your quail include nightshade, foxglove, oleander, lily of the valley, azalea, holly, hydrangea, iris, and sago palm. Macadamia nuts are also toxic. If your quail free-range or have access to a garden, check the area for these plants. Many common ornamentals and houseplants pose risks. Chocolate, caffeine, and alcohol are harmful as well, though these are less likely to end up in a quail feeder.
Salty, sugary, and heavily processed human foods should also stay out of the pen. Quail have tiny bodies and limited ability to process excess sodium or sugar.
Water Matters More Than You Think
A laying quail drinks roughly twice the volume of water as she eats in feed. Even mild dehydration can slow or stop egg production within a day or two. Fresh, clean water should be available at all times in a shallow dish or nipple waterer. In cold weather, check that water hasn’t frozen. In hot weather, refresh it at least twice daily to prevent bacterial growth. Adding a splash of apple cider vinegar (roughly one tablespoon per gallon) is a common practice among quail keepers to support gut health, though the feed itself should remain the nutritional priority.
Lighting for Consistent Production
Diet alone won’t sustain egg production if your quail aren’t getting enough light. Quail need 14 to 16 hours of light per day to maintain their laying cycle. During shorter winter days, supplemental lighting with a simple LED bulb on a timer bridges the gap. The light doesn’t need to be bright, just consistent. Running lights 24 hours a day seems like it would help, but it actually increases stress and can suppress laying over time. A predictable cycle of 14 to 16 hours of light followed by 8 to 10 hours of darkness mimics the long days of peak breeding season and keeps hormonal signals steady.
Place the timer so lights come on early in the morning rather than extending the evening. This prevents birds from being caught on high roosts or away from shelter when lights suddenly shut off.
