Breeding methods of free-range chickens
The first choice is to choose a suitable breed, which is generally dominated by native chickens; then the henhouse should be built on a site with convenient transportation, leeward, adequate light, normal drainage and irrigation, and no stagnant water; feed is best mixed feed, such as corn, pumpkin, sweet potato, rice, cassava, etc.; finally, do a good job in epidemic prevention, so as not to affect the efficiency of breeding.
1. Breed selection: the breeds of free-range chickens are mainly native chickens, such as Luhua chicken, Sanhuang chicken, black-bone chicken, green shell laying hen and so on, because the native chicken has high market demand, strong growth ability and strong disease resistance.
2. To build a chicken house: the chicken house should be built in a place with convenient transportation, leeward, adequate light, normal drainage and irrigation, and no stagnant water. The chicken house should do a good job in the planning of the lounge and sports ground, and then prepare the sink, food trough and temperature control facilities.

Epidemic prevention should be done well so as not to affect the efficiency of breeding. Remove chicken manure regularly every day, disinfect the chicken house regularly, do not feed deteriorated feed and drinking water, and control the breeding density.
