Six Hens: The Honest Math of Backyard Chickens

Every sovereignty journey seems to arrive, sooner or later, at six hens in the backyard — and for good reason. Chickens are the gateway livestock: small enough to learn on, forgiving enough to survive your learning, and productive enough to matter. They also come wrapped in more romantic misinformation than any animal since the horse. So before the breed lists and coop tours, let's do what we always do here: run the numbers.

Part oneWhat six hens actually produce

A quality laying breed in her first year gives 250–300 eggs — call it five a week. Six hens therefore produce roughly two dozen eggs a week at peak, which out-supplies most families comfortably. But the curve matters: production drops around 15–20% per year, pauses entirely during the autumn molt (around 18 months old, then yearly), and slows or stops in deep winter unless you supplement light. A five-year-old hen is mostly a pet with opinions. Plan the flock like the asset it is: two or three new pullets every year or two keeps the egg curve flat while the elders age into the stewpot or the retirement they've earned — decide which farm you're running before you name anybody.

Add a $600 coop spread over five years and the true number is $4–6 a dozen. So no — you will not beat the supermarket's factory floor price. What you get instead: eggs from hens you fed, a protein supply that ignores supply chains, the best composting accelerant in agriculture, and a food system whose entire chain of custody is your backyard. That's what you're buying. It happens to come with breakfast.

Part twoThe coop: four numbers and a latch

• 4 sq ft per bird inside, 10 per bird in the run. Generosity here prevents the pecking, feather-pulling, and egg-eating that cramped birds invent to pass the time.
• One nest box per 3–4 hens, darker and lower than the roost — or they'll sleep (and poop) in them.
• 8–12 inches of roost per bird, higher than the nest boxes, because chickens sleep as high as they're allowed.
• Ventilation above roost height — a chicken exhales a surprising amount of moisture, and damp air, not cold air, is what causes frostbitten combs. Vents up high, no drafts at bird level.

Site the coop in shade if you can get it — heat kills more chickens than cold ever will — and put the whole arrangement close enough to the kitchen door that winter chores stay short. Distance is the number-one predictor of neglected livestock.

Part threePredators: the war you're actually in

Everything eats chicken. Raccoons, foxes, hawks, neighborhood dogs, weasels that fit through a hole the size of a quarter. The defense is a short list, executed without exceptions:

• Half-inch hardware cloth, not chicken wire. A raccoon opens chicken wire like a bag of chips and will reach through any mesh a paw fits — half-inch stops the reach too. Chicken wire's only legitimate job is keeping chickens out of the lettuce.
• Defeat the diggers: bury the mesh 12 inches down, or better, lay an 18-inch horizontal apron outward from the wall — diggers start at the wall, hit mesh, and give up.
• Cover the run — netting or mesh overhead ends the hawk problem completely.
• Two-step latches. Raccoons open hook-and-eyes, deadbolt slides, and simple hasps. A carabiner through a hasp defeats them. This is not folklore; it's the most common way flocks die.
• An automatic coop door ($60–150, light-sensing) closes at dusk whether you remembered or not. Best money in the whole build — most massacres happen the one night someone forgot.

Part fourFeed, scraps, and the loop that pays

The flock's foundation is a 16%-protein layer feed, free-choice, with two side dishes: grit (they have no teeth; stones in the gizzard do the chewing) and oyster shell in a separate dish (calcium on demand for shell-building — offered separately so each hen doses herself). Kitchen scraps are a supplement, not a diet: treat the 90/10 rule as law or egg production quietly sinks. Skip the short list of genuinely bad scraps: raw dry beans, avocado skins and pits, anything moldy, and salty processed leftovers.

Now the part that makes the whole operation pencil out: a hen is a composting appliance that emits eggs. Six hens produce roughly 15 pounds of manure a week — too "hot" (nitrogen-rich) to apply fresh, but composted for four to six months with their carbon-rich bedding, it becomes the exact fertility engine the calorie garden is missing. Scraps and garden waste in; eggs, tilled soil (they'll destroy a spent garden bed for fun, eating pests as they go), and finished compost out. Close that loop and the flock isn't a cost center anymore — it's infrastructure.

Part fiveWinter, sickness, and the calendar

Winter: the rule is dry and draft-free, never heated. A heat lamp in a wooden box full of dust and feathers burns down coops every single year, and an acclimated bird in a well-ventilated coop laughs at zero degrees. Deep-litter bedding (keep adding carbon, stir occasionally, clean out in spring) generates gentle compost heat on its own. The real winter problem is water: a heated dog bowl or plug-in base solves it if you have power; twice-daily swaps if you don't. If you want winter eggs, a light on a timer bringing the coop to 14 hours of total daylight keeps hens laying; skipping it gives them the natural rest their bodies prefer. Either choice is defensible — make it deliberately.

Health: chickens hide illness (prey animals), so watch behavior, not symptoms: a hen standing apart, fluffed at midday, is your early warning. Provide a dust-bath (dry dirt plus a little wood ash) and they'll handle their own mite prevention; check under wings and around vents monthly anyway. Quarantine any new adult bird for 30 days — the fastest way to lose a flock is to import one bargain hen with respiratory disease. And find the nearest chicken-literate vet or extension office before you need one.

AppendixBefore the first chick arrives

• Local ordinance read: hen limit, rooster rule, setbacks, permit. (Typical urban allowance: 4–6 hens, no roosters.)
• Coop built or bought: 4/10 sq ft rule, vents above roost, boxes below it.
• Every opening covered in ½″ hardware cloth; apron laid; carabiners on latches.
• Automatic door installed and tested for a week.
• Feed, grit, oyster shell, and a dust bath in place.
• Compost bay ready for the bedding — the loop starts on day one.
• Plan written for years 3–5: replacement pullets, and what "retirement" means on your farm.

Start with day-old chicks in spring (a heat plate, a stock tank, six weeks of brooding) or point-of-lay pullets if you want eggs by summer. Either way, six is the right first number: enough to matter, few enough to know each bird's politics. You'll be surprised how much politics there is.
