The experiment was conducted to study the development of Gonads in quail embryos. The eggs of Japanese Quail are incubated in BOD incubator at 35 ^oC and 60% Relative Humidity. The embryos were cut out, fixed, paraffin sectioned and stained with Heamatoxylene-Eosin. The result shows that the formation of ovaries starts from 4^th day of incubation. It matures till 17^th day of incubation. The testis starts developing by showing the epididymal linings on 5^th day. These results established the basic groundwork for the research of the development of other endocrine glands of quail as well as other poultry.
