Quick Answer
You do not need one nesting box per hen. Plan on one box for every 4 to 5 hens — so 2 boxes for 6 to 8 hens, 3 boxes for 12 hens, and 4 to 5 boxes for 20 hens — and always have at least 2 boxes, even for a tiny flock, so a broody hen cannot block the only box. If you keep broody-prone breeds, or your hens lay heavily every day, use the tighter ratio of one box per 3 to 4 hens. Do not be surprised when every hen queues for the same favourite box anyway: hens like to lay where other hens have laid, and sharing is normal.
The Ratio, by Flock Size
| Hens | Boxes | If broody-prone or heavy layers |
|---|---|---|
| 1–4 | 1–2 boxes (1 per 4–5) | 2 boxes |
| 5–8 | 2 boxes | 2–3 boxes |
| 9–12 | 3 boxes | 3–4 boxes |
| 13–16 | 4 boxes | 4–5 boxes |
| 17–20 | 4–5 boxes | 5–6 boxes |
| 21–24 | 5–6 boxes | 6–8 boxes |
The reason the ratio works is timing. A hen spends roughly 20 to 30 minutes in the box to lay, and most hens lay before noon, but they do not all need the box at the same instant. Hens also lay on different days — a good layer gives 4 to 6 eggs a week, not 7 — so a box that serves 4 to 5 hens is rarely genuinely overbooked. Larger flocks can even stretch toward one box per 6 hens, but for a beginner flock, 1 per 4 to 5 is the safe, comfortable standard, matching guidance from sources such as Utah State University Extension.
Why One Box Per Hen Backfires
Giving every hen her own box sounds generous, but it creates problems. Extra boxes mostly sit empty, waste coop space, and — more importantly — hens start sleeping in them. A hen that sleeps in a box fills it with droppings overnight, so the next morning’s eggs land in a dirty nest. Too many boxes can also encourage broodiness, since a quiet, undisturbed box is exactly what a broody hen wants. Three to five hens sharing a box teaches them the box is for laying, not for living in.
The other surprise for new keepers is the favourite box. Give six hens three identical boxes and they will still queue for one of them, sometimes two hens squeezing in together. That is normal flock behaviour, not a sign that you need more boxes. Add a box only if you see real trouble: hens laying on the floor or in the run, two hens fighting over a box, or a broody hen blocking the only available nest for days.
What Size Box, and How High
A box should feel snug and hidden, not roomy. A hen needs to turn around and settle, but a box so large that two hens pile in together leads to broken eggs.
| Hen type | Box size | Entry | Height off the floor |
|---|---|---|---|
| Bantams | 10 × 10 × 10 inches | 8–9 inches | 12–18 inches |
| Standard hens | 12 × 12 × 12 inches | 10–12 inches | 18–24 inches |
| Large breeds (Brahma, Jersey Giant, Cochin) | 14–16 inches each way | 12–14 inches | 12–18 inches |
Height matters as much as size, and one rule overrides all the others: nest boxes must be lower than the roosts. Chickens sleep in the highest spot they can reach. If the boxes sit above the roost bars, hens will sleep in them and fill them with droppings. Keep roost bars about 2 to 3 feet up, a good foot above the top of the boxes, and roosts no more than about 3 feet off the floor. Heavy breeds and older hens jump poorly, so mount their boxes lower — 12 to 18 inches — or add a small landing perch or ladder in front.
Add a 4- to 6-inch lip across the bottom of the opening to hold bedding and eggs in, and slope the roof at about 45 degrees so nobody perches on top of the unit. If you stack boxes in rows, keep the top row below the roosts and add a landing perch in front of each row.
Where to Put the Boxes
- In the darkest, quietest corner of the coop — away from the pop door, windows, and the busiest traffic.
- Inside the coop, not the run, so eggs are protected overnight and out of the weather.
- Not under the roosts. Anything below the roost bars gets droppings overnight.
- Easy for you to reach. Boxes with outside access and a hinged, latching lid make collecting and cleaning far easier — and raccoons can open simple hooks, so use a carabiner or two-step latch.
- Out of drafts and direct sun, for a stable, shaded laying spot.
A simple fabric curtain over the front — a strip of feed-sack fabric cut into vertical slits — makes the box darker and more private, which many hens love. It can also cut down on egg eating, since hens cannot see the eggs as easily. Roll the curtain up for the first few days so hens get used to the box, then let it down.
Bedding, Cleaning, and Materials
Use 3 to 4 inches of bedding — enough to cushion eggs without spilling over the lip — and top it up whenever it gets flattened or kicked out.
- Pine shavings: Soft, absorbent, easy to find; hens kick it out.
- Straw: Cheap; hens love shaping nests in it; can hide mites if left too long.
- Hemp bedding: Very absorbent, low dust, composts well; costs more.
- Nest pads or liners: Easy to shake out and wash; good for roll-away boxes; less cosy for broody hens.
- Shredded paper: Free; gets soggy and mats down.
Avoid cedar shavings: their strong oils are hard on chickens’ lungs. Pull out any dirty or wet bedding as soon as you see it, and do a full change every 2 to 4 weeks, checking the corners for mites each time.
Roll-Away Boxes: Worth It?
A roll-away box has a floor sloping about 8 to 12 degrees toward the back, so the egg rolls into a covered tray after it is laid. Eggs stay cleaner, hens cannot peck at them, and broodiness drops because there are no eggs to sit on. The trade-off is that hens do not always take to them straight away, and you can only use a thin nest pad instead of deep bedding. Worth considering if you have an egg eater or sell eggs — but for most beginners, a standard box with clean bedding does the job.
Getting Hens to Actually Use the Boxes
Have the boxes ready by the time pullets are about 16 weeks old — before laying starts at roughly 18 to 22 weeks. Then: add a fake egg or golf ball to each box (hens copy each other); keep boxes clean and fluffy; make them dark and private with curtains or a dimmer corner; keep roosts higher than boxes so hens do not sleep in them; and keep hens in the coop until late morning for a week or two, since most hens lay before noon. If a hen will not leave the box at all, she may be broody — puffed up, growling, sitting tight even with no eggs under her. A broody hen blocks a box for weeks, which is exactly why a spare box matters, and why broody-prone breeds deserve the tighter 1-per-3-to-4 ratio.
When to Add (or Remove) a Box
Add a box when: hens lay on the floor or in the run, two hens regularly fight over one box, a broody hen has blocked the only spare, or you add new layers. Do not add one just because hens all use the same favourite — that is preference, not shortage — and do not add boxes to fix a location problem: a box in a bright, busy, drafty spot will stay empty no matter how many you install. Move it to a dark, quiet corner first. Too many boxes shows up as empty boxes doubling as sleeping spots and wasted coop floor space.
Frequently Asked Questions
Do chickens need nesting boxes at all? Technically no — a hen will lay in any quiet, hidden spot where she feels safe. Boxes are mostly for us: clean eggs in one place, easy to collect, and protected from predators and breakage.
Can I use a bucket, crate, or old drawer as a nesting box? Yes, if it is sturdy, the right size, and easy to clean — milk crates, cat litter pans, five-gallon buckets on their sides, and old dresser drawers all work, provided the size, lip, and height rules above are met.
Why are my hens sleeping in the nesting boxes? Because the boxes are higher than the roosts, or the roosts are missing, too low, or too narrow. Raise the roosts above the boxes and the sleeping problem usually fixes itself. Clean out the soiled bedding the same day.
How many boxes do I need for 6 hens? Two boxes. For 10 hens, three boxes; for 12 hens, three boxes; for 20 hens, four to five boxes. Always keep at least two, even for a small flock.
The Bottom Line
One box per 4 to 5 hens, sized 12 inches for a standard hen, mounted 18 to 24 inches off the floor and always lower than the roosts, with 3 to 4 inches of clean bedding in a dark, quiet corner — that is the whole formula. Add a spare for broody season, a fake egg to show pullets where to lay, and a curtain if your hens like extra privacy. Get those details right and the daily egg hunt in the bushes is over.
