Feed Inventory: Stock, Deliveries and Where Feed Disappears

How to log feed in and out, reconcile stock, calculate days of cover, and find where feed is going somewhere other than into the birds.

Feed is the biggest expense, and it’s the thing that most often “disappears.” Not because someone steals it, but because nobody knows how much there should be. Simple stock records answer two questions: will the feed last until the next delivery, and is any of it going somewhere other than the birds?

The core equation

Formula

Opening stock + delivered − fed to birds = closing stock

If the actual stock in the shed is less than the calculated figure, the difference is loss. If it’s more, a feeding was recorded that didn’t happen.

What to record

Reconciliation

Once a week, or at least once a month, weigh or count the bags and compare with the books. A difference up to 1–2% is weighing error. More than that, look for the cause:

CauseHow to check
Spillage from feedersFeed on the litter, feeders overfilled or hung low
Rodents and wild birdsDroppings and gnaw marks by the bags, sparrows in the house
SpoilageCaking, moldy smell, wet floor in the store
Recording errorsA feeding entered twice, or a delivery never entered
Inaccurate scalesCheck with a known weight or a bag of known weight

Days of cover

Formula

Days of cover = stock on hand ÷ average daily use

Order feed when the stock covers the delivery time plus a few days in reserve. But don’t keep more than 3–4 weeks’ worth: feed loses vitamins and can get damp. Use grows as the birds grow, especially broilers, so calculate from the last week, not the monthly average.

Storage

  1. Bags on pallets, not on concrete and not against the wall.
  2. Use what arrived first, first.
  3. Closed bins or a rodent-proof room.
  4. Dry and cool: heat and moisture destroy vitamins and breed mold.

Stock and money

Feed in the store is money that hasn’t yet turned into eggs or meat. Cost per egg is based on the feed the birds ate, not the feed you bought (on cost). If you cost by purchases, a month with a big delivery looks like a loss and the next one like a windfall.

Stock in the app

In EggPulse deliveries and feedings update the stock automatically, and feeding by recipe deducts each ingredient by its share of the mix. The app shows how many days the stock will last at the current rate, and warns when stock falls below the minimum or it’s time to order more.
