Hello again! As I have posted before, I have 4 growing ducklings about 9wks old. They have been moved to a temporary outdoor enclosure with house and have been in there for about 2 wks. They seem to have figured out the going inside at night business and have been doing so routinely for the last week. Ultimately want to free range them, but they must return to house at night to avoid predators. Will they continue to do so after fence comes down? How long must this routine continue before i let them roam?
