The invention discloses an under-forest ecological breeding method for promoting the growth of Ma chicks. The method comprises the steps of building a henhouse in a sandy woodland; carrying out indoorbreeding on 1-10-day-old Fufengma chickens, and enabling the chickens to freely eat first-stage feed and drink a nutrient solution; breeding 11-25 day-old Fufengma chickens under a forest, enabling the chickens to move freely, and separately feeding the chickens with second-stage feed 5 times per day at 6-8 o'clock, 10-11 o'clock, 12-13 o'clock, 15-16 o'clock and 18-20 o'clock, and enabling the chickens to drink a Chinese herbal decoction; enabling 26-50-day-old Fufengma chickens to freely eat third-stage feed and drink spring water, and adopting a mode of combining indoor breeding with under-forest breeding; adopting an under-forest breeding mode in the time interval from 8 o'clock to 18 o'clock in the period from May to October every year, and adopting an indoor breeding mode in the rest of time; adopting the under-forest breeding mode in the time interval from 10 o'clock to 16 o'clock in the period from November of each year to April of the next year, and adopting the indoor breeding mode in the rest of time; disinfecting the henhouse every week and killing mosquitos and rats.
