Enter the number of quail, the coop space per quail in square feet, and the run space per quail in square feet. The calculator gives the coop area, the run area, the total area, and the fencing length for a square run of that run area. Use the type table below to pick allowances: Coturnix quail suit about 1 sq ft of coop each, while larger, wilder bobwhite quail need more. These are planning estimates, not veterinary advice.
A quail housing calculation has two allowances. Coop area = quail × coop space per quail. Run area = quail × run space per quail. Total area = coop area + run area. If the run is square, its fencing length = 4 × sqrt(run area).
Worked example: 12 quail at 1 sq ft of coop each need a 12 sq ft coop. At 2 sq ft of run each they need a 24 sq ft run. The total area is 36 sq ft, and a square run of 24 sq ft needs about 20 ft of fencing (4 × sqrt(24) = 19.6, rounded up). A quail coop for 6 quail at the same allowances is 6 sq ft of coop and 12 sq ft of run, 18 sq ft in total. A quail coop for 25 quail is 25 sq ft of coop and 50 sq ft of run, 75 sq ft in total.
Enter the number of quail in your flock. Enter the coop space per quail in square feet for the sheltered, roofed part of the housing. Enter the run space per quail in square feet for the outdoor exercise area. Press Calculate to see the coop area, run area, total area, and fencing for a square run.
Check the result against the quail coop dimensions you can actually build: a coop that meets the area target but is only 1 ft wide leaves no room for feeders, waterers, and hiding spots. If your run is rectangular, the fencing figure changes slightly, but the coop and run area figures stay the same.
Quail housing requirements start with the bird itself: quail types differ in size and temperament, so one allowance does not fit all. Coturnix quail space requirements are the most quoted, because Coturnix are the common egg and meat bird:
| Quail type | Coop per quail | Run per quail | |---|---|---| | Coturnix (Japanese) quail | 1 sq ft | 2 sq ft | | Button (Chinese painted) quail | 0.5-1 sq ft | 1-2 sq ft | | Bobwhite quail | 2-3 sq ft | 4-6 sq ft | | California valley quail (aviary birds) | 2 sq ft | 6-10 sq ft |
How many quail per square foot is the same question asked backwards: at 1 sq ft of coop each, one quail fits per square foot of coop, and at 2 sq ft of run each, one quail fits per 2 sq ft of run. Bobwhite quail are wilder and more flighty than Coturnix quail, so they need the extra room and a taller, softer-roofed pen to avoid head injuries when they flush. A quail aviary size for a mixed ornamental flock should use the largest, shyest species in it as the guide, not the average.
Quail housing works best as a dry, draught-free coop joined to a secure run, or as a single large cage or aviary with a sheltered end. Quail do not roost on perches like chickens: they sleep on the ground in groups, so floor area matters more than height, and the roof should be soft netting or padded in tall pens to prevent head injuries when birds flush upwards. Note the density debate: commercial stacked-pen keepers sometimes use 3 birds per square foot in low pens, while aviary and ground setups need about 1 bird per square foot of floor or more, which is why this calculator separates coop space from run space instead of giving a single density.
Quail feeder and waterer space must come on top of the area figures, not out of them: allow one feeder and one waterer per 10 to 15 birds, placed where every bird can reach them without crossing the whole pen. Quail nesting boxes are optional, because quail usually lay on the ground in a quiet corner with straw or hay: a few dark, sheltered laying corners beat formal boxes. Quail coop bedding of straw, wood shavings, or sand should stay dry, and wire floors, where used, need a solid resting area so feet stay healthy.
The quail male female ratio shapes how peaceful a pen is. For Coturnix quail kept for eggs, one male to 4 or 5 females is the usual ratio: more males mean fighting, feather pulling, and over-mating, while too few males mean lower fertility. Bobwhite and ornamental species are often kept in pairs or in one-male groups for the same reason.
When you plan space, count every bird, including extra males you intend to keep apart: a spare male needs his own pen, not a corner of the main pen. Young quail can be brooded together, but separate the sexes or the extra males before maturity, or the flock balance breaks down fast. A calm flock lays better, grows faster, and wastes less feed.
Quail coop predators include rats, snakes, raccoons, dogs, cats, and birds of prey, and quail are small enough that even a rat can kill them. Use half-inch hardware cloth, not chicken wire, on every opening, bury or skirt it at the bottom, and lock doors with latches raccoons cannot open. A solid roof keeps out aerial predators and keeps the bedding dry.
Do quail need a run in winter? Quail cope with cold well in a dry, draught-free coop with deep bedding, and most breeds need no heating, though water must be kept ice-free and wind must be blocked. In hard freezes, close the run and keep birds in the sheltered coop with extra bedding. Clean droppings and wet bedding weekly at least: quail droppings are wet and ammonia builds up fast in small, enclosed coops, which damages lungs and feet.
Do quail need a run? No, quail can live their whole lives in a roomy indoor cage or aviary, but a run gives them sunlight, fresh air, dust bathing, and foraging, all of which improve feather condition and behaviour. If you keep quail indoors only, raise the coop allowance and add dust baths, hiding spots, and enrichment so the birds can behave naturally.
A run is most valuable for Coturnix and bobwhite quail kept for eggs and meat, because exercise and sunlight support laying and growth. For button quail kept as indoor pets, a large cage with a solid floor, hiding spots, and a dust bath can be a complete home. Whichever route you choose, size it with this calculator first: a pen that is too small shows up as feather pecking, fighting, and poor laying within weeks.
Coturnix quail need about 1 sq ft of coop each plus about 2 sq ft of run each. Button quail need less (0.5 to 1 sq ft of coop), while bobwhite quail need more (2 to 3 sq ft of coop plus 4 to 6 sq ft of run).
At the usual Coturnix allowance of 1 sq ft of coop per bird, one quail fits per square foot of coop. In the run, one quail fits per 2 sq ft at the usual run allowance. Larger or wilder species need more space per bird.
At 1 sq ft of coop and 2 sq ft of run each, 12 quail need a 12 sq ft coop and a 24 sq ft run, 36 sq ft in total, with about 20 ft of fencing for a square run.
At the same allowances, 6 quail need a 6 sq ft coop and a 12 sq ft run, 18 sq ft in total. A 2 ft by 3 ft coop joined to a 3 ft by 4 ft run meets that target.
At 1 sq ft of coop and 2 sq ft of run each, 25 quail need a 25 sq ft coop and a 50 sq ft run, 75 sq ft in total. Split a flock this size into two pens if you keep more than one male.
For Coturnix quail, one male to 4 or 5 females is the usual ratio for eggs and fertility. More males cause fighting and over-mating. Bobwhite and ornamental quail are often kept in pairs.
Not really: quail usually lay on the ground in a quiet, dark corner with straw or hay. A few sheltered laying corners work better than formal nesting boxes, which most quail ignore.
No, quail can live indoors in a roomy cage or aviary, but a run adds sunlight, dust bathing, and foraging that improve feather condition and behaviour. Indoor-only birds need a larger coop allowance plus dust baths and hiding spots.
Use half-inch hardware cloth on every opening, not chicken wire, bury or skirt it at the bottom, use raccoon-proof latches, and add a solid roof. Rats, snakes, raccoons, dogs, cats, and birds of prey all threaten quail.
Yes, most quail cope with cold in a dry, draught-free coop with deep bedding, without heating. Keep water ice-free, block wind from the run, and close birds into the sheltered coop during hard freezes.
Straw, kiln-dried wood shavings, or sand all work if kept dry. Change wet bedding weekly, because quail droppings are wet and ammonia builds up fast in small coops.
Size a cage by the same rule: about 1 sq ft per Coturnix quail. A cage for 6 Coturnix quail should be at least 6 sq ft of floor, with room for feeders, a waterer, a dust bath, and a hiding spot on top of that.
