questions: asking about deep liter system 
 answers:   recommended to  litter management: litter materials such as wood shavings; saw dust, paddy husk, peanut shell, paddy chaff, chopped straw and such other materials that absorb moisture well can be used depending upon the cost and availability. spread the litter to a depth of 5 cm on the floor before introducing chicks and build it up to a depth of 15 cm by adding litter material, at the rate of about 2 cm per week. this would require approximately 10 kg of litter material/sq.meter. litter should be raked thoroughly at frequent intervals, say at least twice a week, during the cold and rainy season, once a week during the hot season and the day after deworming. litter should be kept dry always. during the cold and rainy season and on the area of floor where watering utensils are placed, special attention should be paid daily to check the litter condition. if required, top-dress with fresh litter. it is desirable to use dry lime at the rate of 10 kg per 10 m3 and rake the litter.
