The present invention relates to feed for raising poultry containing natural sulfur, a method for raising poultry using feed containing natural sulfur, and an egg produced by using the same. The feed for raising the poultry of the present invention is produced that a chicken is raised with the feed for the poultry for six weeks, the natural sulfur is gradually supplied to the feed to allow the chicken to be fed, thereby reducing a mortality rate, and the natural sulfur is continuously supplied to the chicken even during a laying period, thereby allowing the chicken to lay the egg containing a large amount of the natural sulfur which is accumulated in a body of the chicken. To this end, the method for raising the poultry according to one aspect of the present invention is that the feed for poultry containing 0.006 to 0.007 wt% of natural sulfur, 0.112 to 0.153 wt% of hardwood charcoal powder, 0.042 to 0.059 wt% of a boxthorn, and 0.037 to 0.047 wt% of Artemisia iwayomogi, with respect to the total weight of the feed, is fed every divided period, after dividing a certain period into several periods, to the chicken passed six weeks since a hatching day, meanwhile, the total weight of the feed is increased depending on a change in the weight of the chicken. Accordingly, the fermented feed produced by mixing the natural sulfur with the feed for the poultry is gradually supplied to the chicken, maximizes tolerance of the chicken for the sulfur, and then gradually increases the amount of the sulfur supplied depending on the growth of the chicken, thereby promoting the growth of the chicken, minimizing the mortality rate, and continuously laying the egg such that the chicken is raised.본 발명은 일반 양계용 사료로 6주간 닭을 사육한 후 점진적으로 천연유황을 사료에 공급하여 먹임으로서 폐사율을 줄이고 산란기간에도 지속적으로 천연유황을 보급함으로써 닭의 체내에 축척되어 있는 다량의 유황성분이 함유되어 있는 계란을 산란시킬 수 있는 천연 유황 성분이 포함된 양계용 사료, 천연 유황 성분이 포함된 양계용 사료를 이용한 양계 방법 및 이를 이용하여 생산한 계란을 제공하는데 목적이 있다.이를 위해, 본 발명의 일 측면에 따른 천연 유황을 포함하는 양계 사료를 이용한 양계 방법은, 부하일로부터 6주가 경과된
