How much chicken feed does the laying hens eat every day?

Before 10 days of age: (day age + 2) g

10-20 days old: (day age+1)g

20-50 days old: grams of material used = day age

51-150 days age: 50+ (day age-50)/2

Breeding chickens over 150 days old: stable over 100g

Egg-laying peak: about 120g

Feeding according to the above calculation method, a hen will consume 8.84kg when it reaches the age of 150 days, and the feed consumption of a layer is 36.5kg in one year, which can basically meet the needs of laying eggs.
