This study was conducted to evaluate the effect of breed, pre-incubation storage days and their interaction on hatching parameters of Arbor acre and Ross breeder hens. A total number of 1200 eggs were collected in three (3) batches and stored for 4 days, 7 days and 10 days before incubation. The experiment was designed as a completely randomized design (CRD) with 2 x 3 factorial arrangements. Data collected on fertility and hatching parameters were subjected to the General Linear Model of SAS®, while significant differences were separated using Tukey's Honestly Significant Difference. Fertility and hatchability of egg's set were significantly influenced by a breed with Arbor acre showing better performance than Ross (P < 0.05). Pre-incubation storage days had a significant effect on the hatchability of fertile eggs, hatchability of egg's set and embryonic mortality (P < 0.05). Eggs stored for seven days produced the best results among the storage days (P < 0.05). In the future, the practice of pre-storage incubation of eggs for 6 − 12 hours can be applied with the 7-day pre-incubation storage period to improve overall egg hatchability and chick quality.
