Which of the following eggs typically has the longest hatching time?

Duck eggs typically have the longest hatching time compared to the others listed. The incubation period for duck eggs generally ranges from 28 to 35 days, depending on the species. In contrast, pigeon eggs usually hatch in about 17 to 19 days, quail eggs around 16 to 18 days, and turkey eggs take about 28 days. This longer hatching time for duck eggs is due to the unique developmental needs of ducklings, which require additional time to develop fully in the egg before hatching. Understanding these incubation periods is crucial for poultry management and breeding practices.
