How Much Does It Cost to Keep Backyard Chickens?
Estimate the monthly cost of a backyard chicken flock, including feed, bedding, supplies, repairs, and the true cost per dozen eggs.
The monthly cost of keeping backyard chickens depends less on the price of the birds than on the system around them. Feed is usually the largest recurring expense, but bedding, supplements, electricity, replacement equipment, repairs, health care, and losses can change the total substantially.
A useful estimate begins with your own feed price and measured consumption. Then it separates normal monthly expenses from occasional costs and startup purchases. That makes the result useful for household budgeting, comparing flock sizes, or setting an egg price without pretending every month will look the same.
Separate startup costs from monthly costs
Housing and equipment can make the first year much more expensive than later years. Record these startup costs separately:
- Coop, run, fencing, and predator protection
- Feeders, waterers, storage containers, and brooder equipment
- Birds, shipping, permits, and initial veterinary or testing costs
- Electrical work, lighting, and weather protection
- Tools and cleaning supplies bought specifically for the flock
You can treat these as one-time household expenses or spread them across their expected useful life. For example, a $1,200 coop used for ten years represents $10 per month before repairs, financing, or the value of labor. That calculation does not make the original cash expense disappear; it simply helps compare long-term costs.
Do not count your own labor as free if the goal is to evaluate a business. For a household budget, track chore time separately even if you choose not to assign it a dollar value.
Calculate monthly feed use
The strongest feed estimate comes from your records:
- Record the weight and price of each bag purchased.
- Record the date a bag is opened and the date it is finished.
- Note feed spilled, spoiled, or consumed by rodents or wild birds.
- Average several ordinary weeks rather than relying on a single day.
If you do not have records yet, begin with the feeding directions for the complete feed appropriate to your birds’ age and purpose. Manufacturer and extension reference amounts are planning points, not guarantees. Intake changes with bird size, weather, production, forage access, feed form, waste, and flock management.
Use this formula once you have a reasonable daily estimate:
Monthly feed needed in pounds = number of birds × ounces per bird per day × 30 ÷ 16
Then calculate:
Monthly feed cost = monthly pounds needed ÷ bag weight × price per bag
The Flock Feed & Egg Cost Calculator performs both calculations and lets you replace its starting assumptions with your own flock numbers.
Add the costs that are easy to overlook
Feed alone is not the cost of keeping a flock. Review receipts and records for:
- Bedding and nest material
- Grit, oyster shell, and other supplies appropriate to the flock
- Egg cartons and cleaning supplies
- Electricity for approved lighting, heated waterers, or brooding equipment
- Water use where it is a meaningful household expense
- Pest control and secure feed storage
- Routine repairs, replacement latches, hardware cloth, and weatherproofing
- Veterinary examinations, diagnostic testing, medications, and biosecurity supplies
- Mortality, replacement birds, and periods when birds consume feed but produce few eggs
- Permits, insurance, processing, or sales expenses where applicable
Read feed and animal-health product labels rather than adding supplements automatically. A monthly budget can include a health-care reserve, but a reserve is not a substitute for appropriate veterinary care.
Build three illustrative flock budgets
The following examples are worksheets, not price claims. They use the calculator’s starting assumptions of four ounces of feed per bird per day and a 50-pound bag costing $19.99. “Other monthly costs” are placeholders for bedding, supplies, utilities, and a repair or health reserve. They exclude startup costs and labor.
| Flock | Feed per month | Estimated feed cost | Other costs | Estimated monthly total |
|---|---|---|---|---|
| 4 hens | 30 lb | $11.99 | $8.00 | $19.99 |
| 8 hens | 60 lb | $23.99 | $10.00 | $33.99 |
| 12 hens | 90 lb | $35.98 | $12.00 | $47.98 |
These examples allow partial bags to be valued proportionally. Cash spending will be uneven because feed is purchased by the bag. A household might spend more in the month it buys two bags and less the next month, even when consumption is steady.
Replace every assumption with a current local price or a measured number before using the estimate to make a decision.
Find the cost per dozen eggs
First total the eggs collected during the month, then use:
Dozens produced = total eggs ÷ 12
Cost per dozen = total monthly flock cost ÷ dozens produced
Suppose the illustrative 8-hen flock costs $33.99 for the month and produces 150 eggs, or 12.5 dozen. Its entered monthly cost is about $2.72 per dozen. That number excludes the coop, equipment, labor, and any expense not included in the $10 placeholder.
Cost per dozen often rises during molt, winter, extreme weather, flock aging, broodiness, illness, or other periods of reduced production. University extension guidance notes that daylight, nutrition, age, molt, stress, and health can all affect laying. A single productive month is therefore a poor basis for an annual claim.
Are backyard eggs cheaper than store-bought eggs?
Sometimes, but low cost is not guaranteed. The answer depends on local retail prices, the cost and lifespan of housing, feed waste, flock productivity, health expenses, labor, and how many eggs the household actually uses.
A fair comparison should use eggs of similar size and quality and should cover a full year. It should also acknowledge benefits that do not appear in the per-dozen calculation, such as enjoyment, education, manure for managed composting, or greater control over husbandry. Those benefits may be valuable without making the eggs financially cheaper.
If eggs are sold, the break-even price is not automatically a legal or sustainable selling price. Confirm current egg-handling, labeling, licensing, tax, zoning, and insurance requirements in your location, and include every business cost.
Review the estimate every month
A simple monthly review is more useful than a detailed budget that is never updated:
- Total feed purchased and estimate the amount actually consumed.
- Add supplies, utilities, repairs, and health expenses.
- Record the month’s egg total.
- Calculate total cost and cost per dozen.
- Write down one unusual factor, such as a heat wave, molt, feed spill, or repair.
- Choose one action for the next month.
Possible actions include adjusting feeder placement to reduce waste, repairing a water leak, planning for a seasonal production change, or replacing an unrealistic budget assumption.
Our guide to chicken flock record keeping explains how to maintain feed, egg, expense, and health records without making daily chores complicated. The Small Flock Recordkeeping Bundle provides printable feed-purchase, expense, egg-production, and monthly-summary pages if you prefer a ready-made system.
Frequently asked questions
What is the biggest monthly cost of keeping chickens?
Feed is commonly the largest predictable recurring expense, but housing repairs or veterinary care can exceed it in an individual month. Measure your own feed use and keep a reserve for irregular costs.
How much feed does one hen eat per month?
There is no dependable amount for every hen and management system. Use the label directions for the correct complete feed as a starting point, then measure the flock’s actual use. Bird size, life stage, production, climate, feed form, and waste all affect consumption.
Should coop cost be included in the cost per dozen?
Include it when you want a full economic cost. Divide the coop’s cost, including necessary improvements, across a realistic useful life and add expected maintenance. You may omit it from a short-term cash budget, but label the resulting cost per dozen clearly.
How long should I track costs before setting an egg price?
A full year captures more seasonal variation than a productive spring or summer month. Continue updating the calculation when feed prices, flock size, production, or local requirements change.
Can I use grocery-store egg prices to set my price?
Retail prices provide context but do not reveal your costs or legal obligations. Calculate your own full cost, research comparable local eggs, and confirm current rules before selling.
