We hatched a duckling two days ago. We had two eggs almost ready to hatch, but unfortunately the other one didn't make it, leaving us only one. The lone duckling, Pippi, seems to have imprinted on us already. We were planning to transfer two ducklings outdoors after a few weeks, but can a single duckling, with already strong imprint, be kept outdoors? I am hoping to introduce Pippi to a flock at nearby school once it is old enough. Please advice on choices that I may have. Thanks!
