How Much Feed Do Cornish Cross Chickens Eat?

Cornish Cross feed consumption increases quickly as the birds grow. One chick will eat about 12.4 pounds of feed by seven weeks, 15.7 pounds by eight weeks, and 20.4 pounds by nine weeks. By ten weeks, that amount increases to roughly 24 pounds per bird.

Use the Cornish Cross feed calculator above to estimate how much feed your entire flock will need. Enter the number of birds you are raising, your planned butcher week, and the weight of each feed bag. The calculator will estimate total feed consumption and round up to the number of full bags needed.

  These numbers are cumulative, meaning they represent the total amount of feed each Cornish Cross Chicken is expected to eat from placement through the selected butcher week. Actual feed use will vary based on flock growth, weather, activity level, feeding routine, and the amount of feed spilled. The calculator does not include feed waste, so consider purchasing extra feed if your birds tend to scatter it or if you want a buffer before processing day. Store unopened bags in a cool, dry place and avoid buying more feed than you can keep fresh.
