The experiment was implemented to identify the effectiveness of aerobic composting of chickm manure and dead chicken over 40 day period through two experimental groups. The main difference of these groups was that the layers of chicken manure were separated by using rice husk in second group and the ratio between chicken waste and rice husk (3.42:1 and 2.5:1 respectively). The results demonstrated that the optimal temperature was obtained from first experimental group, where temperature reached a peak of 74.5oC after 4 days during process of experiment. This group was also advantgeous that rice husk quantity could be saved. After 40 day period of experiment, Salmonella was negative, the quantity of Coliform and E.coli declined significantly. Coliform decreased from approximately 4.05.107 to less than 102. Similarly, E.coli also declined to less than 3 per MPN. The first application of aerobic composting to treat dead chicken demonstrated the potential and effectiveness of this method. Dead chickens were completely decomposed after 20 day. NH3 and H2S were not detected at 1 m, 5m, 10m and 20 m distances from experimental site.
