How Much and When to Feed Chickens [Part 1]

Feeding backyard chickens is an imprecise science. It’s difficult to tell someone how much to feed their chickens, or even when to feed them. So many variables are involved: the type of chickens, whether they’re growing or laying, how active they are, how neat you are, the type of feeders you have, the number of free-loading pests you support, and the weather.
Use these guidelines for feeding your chickens, but alter them for your own flock.
Our modern, high-production egg breeds convert feed to eggs very efficiently, especially if they’re fed a ration formulated for laying hens. After they’re laying well, it takes about 4 pounds of a quality feed of 16 to 18 percent protein to produce a dozen eggs. The breeds kept for dual purposes (eggs and meat) generally have heavier body masses to support and need more feed to produce a dozen eggs than a lighter production breed.
It takes about 2 pounds of feed to produce 1 pound of body weight on a growing meat-type bird. So if a broiler weighs about 6 pounds at 10 weeks, it will have eaten about 12 pounds of feed. Remember that it ate less when it was small, and the amount of feed consumed increased each week. A medium-weight laying hen will eat about 1/4 pound of feed per day when she begins producing. These are rough estimates, but they give you some idea of what to expect.

Chickens eat more in cold weather and less in hot weather.
