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.
Quail incubation periods vary by species. Bobwhite hatch in 23 to 24 days, Coturnix in just 17, for example. Eggs need to be placed in the incubator with the large end slightly elevated.Then, the egg needs to be turned on its axis five to seven times per day.umidity. The humidity in the incubator needs to be maintained between 55% and 60% relative humidity. The development of the embryo relies on liquid in the egg evaporating over the incubation period. Too much humidity and the albumen will not dry sufficiently and the developing chick will drown.
