Hatchability is important parameter that should be studied before distributing hatching eggs. A study was therefore conducted to compare hatching parameters of four breeds of chickens at Research Center using standard method. A total of 6000 hatching eggs; 1500 from each parent stock namely Local Horro, Fayoumi, Lohmann silver and Potchefstroom Koekoek were collected in 3 batches and hatched. Egg weight showed significant difference among 4 genotypes at (p0.05). Genetic difference results in difference in fertility and hatchability.
