  1. 1.5 hours

  2. 2 hours

  3. 2.5 hours

  4. 3 hours

The correct answer is: 2.5 hours

The length of time for food passage in an egg-laying hen is generally recognized to be about 2.5 hours. This time frame refers to the duration it takes for the feed consumed by the hen to move through its digestive system before contributing to egg production. This process is important as it ensures that the hen receives the necessary nutrients efficiently, which are then utilized for the production of eggs. Understanding this time frame can be useful for farmers and poultry handlers as it helps manage feeding schedules and optimize the health and productivity of the hens, ensuring that they are nourished appropriately for optimal egg-laying. It reflects the efficiency of the hen's digestive system and emphasizes the importance of careful diet formulation in poultry management.
