Question 1: At what age is a duckling most likely to imprint?
Based on the information you provided, the most likely age for a duckling to imprint is:
24 hours
Question 2: In a natural setting, all the eggs in a duck nest usually hatch within a few hours. Shortly after all the ducklings have hatched, and periodically thereafter, the mother duck will lead them all to a food source and then back to the nest to rest. Given this situation, which ducklings are most likely to imprint on their mother?
Based on the information about critical periods for imprinting, the most accurate response is:
Only those that are 10-18 hrs will successfully imprint.
This assumes that imprinting occurs more effectively within a specific critical period.
If you have more specific data or findings from the research you mentioned, please share them, and I can provide more tailored responses.
