Popis: The study was design to identify effect of Guinea fowl hatchable egg source on fertility and hatchability and egg physical characteristics. Hatching eggs are primarily subject to assessment of external characteristics. The most important characteristics determining whether eggs are suitable for incubation are their weight, shape, and eggshell condition. Six hundred Guinea fowl eggs were purchased from two reputable breeder farms in Northern Nigeria BirninKebbi and Southern Nigeria Saki consisting of 300 eggs from each source. The eggs collected were stored for seven days at temperature between 16o c-20 oc and selected for incubation in an automated incubator to determine the percentage overall keet hatched, dead in shell, dead in germs, infertile, fertile but not hatched and weak in shell. The results showed that, the hatching rate of the eggs was mostly found to be in the range of 60% for Saki and 68% for BirninKebbi. From the measurements of egg weight, egg length, egg width and egg shape index, egg length and egg shape index (ESI) were significantly (p
