The invention discloses a method for breeding guinea fowls at a breeding period. The method is characterized by including the steps that the metabolic energy of 22-56-day-age fodder at the early stageof breeding is higher than 12.13 megajoule/kilogram, fodder limiting is conducted, illumination is formed, breeding density is formed, and grazing is conducted. When 25-week-age bred fowls are bred through the method, the average individual weight can reach 1,800 grams, robustness is realized, and productivity is good.
