As a guide it takes about 15 lbs of feed to raise a white egg layer pullet (from chick to first egg), an estimated 18 lbs of feed to raise a brown egg layer pullet (from chick to first egg) and approximately 10 lbs of feed to raise a Cornish cross broiler to 7 weeks of age. When a standard size chicken (example: Rhode Island Red hen) is at 6 months of age it will consume 1.5 lbs of feed weekly.
