The purpose of this Cooperative Agreement financed by the U.S. Department of Labor is to: 1  develop population estimates for the prevalence of children working in the worst forms of child labor in the cocoa growing areas of Cote cÃ´te'd lvoire And ghana based on data From Tulane'university s earlier survey in/2008,  2009urvey research on child labor in West African Cocoa Growing Areas: An Introduction from Tulane University Law School Payson Center for International Development.
The incubation period is 16 1/2 to 17 1/2 days. The duration of incubation may range from 16 to 18 days depending upon temperature, humidity and genetic variability. Some farmers in Singapore transfer the developing eggs to a separate hatcher on 15th day of incubation.
Japanese quail eggs incubated at the lower humidity presented the highest level of hatchability (79%) compared to intermediate and high humidities. Egg weight loss was respectively 11.96%, 8.94%, and 4.89% for low, intermediate and high humidity groups.t the 15th day of incubation (360h) egg turning was stopped and the eggs were transferred to the hatcher that maintained the same temperature and relative humidity until hatch. All eggs were weighted on 1st, 5th, 10th, and 15th day of incubation and quail chicks at hatch.
