What changes the number

  • Winter: up to a third more. The same bag lasts 15 days in a cold month.
  • Waste: an open or ground-level feeder loses 10 to 20 percent. A treadle feeder pays for itself in a few bags.
  • Breed: bantams need about half, so a bag lasts 40 days; heavy breeds a third more, so 15 days.
  • Pasture: good forage in season trims 10 to 20 percent. Bare dirt trims nothing.

Spills and rodents usually take 10 to 20 percent of a bag. A treadle feeder is the most direct way to cut that cost.

Common questions

How much do 10 chickens eat per day?

About 2.50 lb (1134 g) of layer feed a day for standard breeds, a quarter pound each. Bantams eat about half; heavy breeds a third more.

How many bags of feed do 10 chickens need per month?

1.5 bags of 50 lb a month, or 18 a year. Buy a size you finish within two months so it doesn't go stale.

Why is my bag running out faster?

Waste, almost always. An open feeder loses 10 to 20 percent of a bag to scratching, wild birds and rodents. Cold weather adds up to a third. A treadle feeder fixes the first; nothing fixes January.

Does free-ranging make the bag last longer?

A little, in a good season: 10 to 20 percent less bagged feed on real pasture. On bare dirt, nothing. Layer feed is still the whole diet; forage is dessert.
