Chicken feed cost calculator, explained

Backyard layer-feed cost runs roughly $4–6 per hen per monthat typical 2026 retail prices. A 6-hen flock costs $25–35/month; 12 hens $50–70/month; 20 hens $80–115/month. The math is the calculator's lb/month output × per-pound feed price. Three levers reduce the cost meaningfully: bag size, source (feed mill vs big-box), and waste reduction. Free-ranging saves 10–30% on top.

Monthly cost by flock size + feed price

Lb/month from the calculator at standard layer baseline. Cost columns assume per-pound retail at $0.44, $0.52, and $0.60 — spanning the typical 2026 range from feed-mill house brand to name-brand pellet at major retail.

Flock	Lb / month	@ $0.44/lb	@ $0.52/lb	@ $0.60/lb
3 hens	20–30	$11	$13	$15
6 hens	40–60	$22	$26	$30
10 hens	66–99	$36	$43	$50
12 hens	79–119	$44	$52	$60
20 hens	132–198	$73	$86	$99

Cost columns use the midpoint of the lb/month range. Heavy- breed flocks (Brahma, Jersey Giant) bump these by ~20%; free-range supplement at 30% drops them by roughly 30%.

Bag size: 25 lb vs 50 lb

50-lb bags cost 15–25% less per pound than 25-lb bags at the same brand. A typical spread:

25-lb bag at $14 retail = $0.56/lb
50-lb bag at $24 retail = $0.48/lb
Per-month savings, 6-hen flock: $4–6/month, $50–70/year

The 50-lb bag wins for any flock using more than 30 lb/month (3+ standard layers). Below 30 lb/month, the 25-lb bag is better — open feed loses palatability within 4–6 weeks, so buying ahead doesn't help. Smaller flocks should size bags to consumption, not to per-pound math.

Source: feed mill vs big-box retail

Local feed mills (look for “feed and seed” in rural-route towns, or your county's Tractor Supply if they stock house brands) sell house-brand layer feed at 20–30% below name-brand retail at the same nutritional spec. A 6-hen flock saving 25% on the bag spends ~$70/year less. Talk to a feed mill before committing to one brand.

Order-of-magnitude pricing in 2026:

Feed-mill house brand (50 lb): $20–24
Tractor Supply house brand (50 lb): $22–28
Major name-brand (Purina Layena, Nutrena Country Feeds, 50 lb): $26–32
Specialty / organic (50 lb): $40–55

Waste reduction: the silent cost lever

Open trough feeders waste 15–30% of feed before any deliberate fix. The calculator outputs feed CONSUMED; what you BUY is consumed plus waste. Three fixes that materially drop monthly feed cost:

Vertical-sided feeders with anti-scratch grills. PVC or galvanized treadle feeders cost $30–60 and reduce waste from ~25% to ~5%. Payback in 6–10 months on a 6-hen flock.
Feeder under shelter or with a rain hood. Open feeders left in rain mold within 12–24 hours; birds reject moldy feed. A simple shed roof or flashing hood costs $10–25.
Galvanized lidded feeder + metal trash-can storage. Rats and mice eat 1–2 lb/day per rat from open feed. Galvanized lidded feeders + storing closed feed in a metal trash can with a tight lid eliminates rodent shrinkage.

Free-range supplement math

A 6-hen flock at $0.52/lb feed pricing pays $26/month at full confinement. Adding 4–8 hr/day run access on lush spring pasture drops commercial feed intake by 25–30% — saving $6–8/month for 4–6 months of growing season. Annual savings ~$30–40 for the typical mid-zone-6 backyard.

Don't confuse this with free-range as primary feed — that doesn't work. Even mostly-ranged flocks need 50%+ of calories from a balanced commercial feed for protein and calcium. The savings are on the supplement portion, not the base ration.

Annual feed budget worksheet

For a 6-hen layer flock at typical 2026 pricing ($0.52/lb, 50-lb bags from a feed mill):

Base annual feed cost: ~$310 (6 hens × $0.52/lb × 100 lb/hen-year)
Free-range savings, 5 months growing season: −$40
Oyster shell free-choice: ~$15 (3–4 bags/year @ $4 each)
Treats / scratch / mealworms: $30–50 (optional)
Estimated annual feed budget: $315–335

That's for active layers in production. Pullets cost less (~60% of layer rate); chicks the first 8 weeks cost much less (~35% of layer rate). Add roughly $40 in starter+grower per chick raised from hatch to point-of-lay.

Run the numbers for your flock

The feed amount calculator outputs lb/day, lb/week, lb/month for your flock plus the right bag size and reorder cadence. Multiply lb/month by your local per-pound feed price to get the monthly cost. Repeat with free-range supplement set to your typical season to see the supplement effect.

Frequently asked

How much does it cost to feed chickens per month?

Roughly $4–6 per hen per month at typical 2026 layer-feed prices ($22–28 per 50-lb bag). A 6-hen flock runs $25–35/month; 12 hens runs $50–70/month; 20 hens runs $80–115/month. Heavy breeds bump cost ~20%; free-range supplement of 4–8 hr/day saves 10–30% in growing season. The single biggest variable is local feed pricing — feed-mill house brands often run 20–30% cheaper than name-brand bagged feed at the same nutritional spec.

What's the cost difference between 25-lb and 50-lb feed bags?

50-lb bags run 15–25% cheaper per pound than 25-lb bags at the same brand and formulation. A typical price spread: $14 for a 25-lb bag = $0.56/lb; $24 for a 50-lb bag = $0.48/lb. The 50-lb bag wins on cost-per-pound for any flock burning through more than 30 lb/month. Smaller flocks (1–3 birds) using less than 25 lb/month should stick with 25-lb bags — open feed loses freshness within 4–6 weeks regardless of bag size.

Does free-ranging save on feed cost?

Yes, modestly. A 4–8 hr/day run-access flock reduces commercial feed intake by 10–30%, depending on pasture quality and season. For a 6-hen flock at $30/month base feed cost, free-range savings runs $3–9/month. Over a year that's $36–108 — meaningful but not transformative. The bigger value of run access is welfare, not feed savings; treat the feed reduction as a side benefit.

Are eggs from a backyard flock cheaper than store-bought?

Per egg, no — almost never. Backyard layer feed at $4–6/hen/month works out to roughly $0.30–0.50 per dozen (assuming 4–5 dozen eggs/hen/month at peak production). Store eggs run $3–6/dozen at 2026 grocery prices. The math is close, and that's BEFORE coop construction, bedding, equipment depreciation. Backyard chickens win on egg quality and self-sufficiency, not unit cost. The 'free eggs from chickens' framing is wrong; budget for $4–6/hen/month and any savings beyond that is a bonus.

How do I reduce chicken feed costs?

Three real levers: (1) Buy the right size bag — 50-lb saves 15–25% per pound vs 25-lb. (2) Buy from a feed mill, not a big-box pet store — house brands at the mill often run 20–30% cheaper than name-brand bagged feed. (3) Reduce waste — open trough feeders waste 15–30% of feed; switch to vertical-sided feeders with anti-scratch grills. Together these three can drop monthly feed cost 30–40% without changing flock or feed type. Free-ranging adds another 10–30% reduction in growing season.

Is organic chicken feed worth the price premium?

Personal value call. Organic layer feed runs 60–100% more than conventional at the same protein spec — a 50-lb bag at $40–50 vs $22–28. The eggs are nutritionally identical at the same protein percentage; organic certification covers input choices (pesticides, synthetic fertilizers), not bird health or egg quality. If you're already paying for organic for your own household reasons, extending that to feed is consistent. If the math is the question, conventional layer feed at the same protein spec produces equivalent eggs at half the cost.
