In July I bought 6 ducklings from the local farm supply company. My kids and I have enjoyed raising these fun and beautiful creatures. We enclosed an area in our back yard with fencing and built them a fairly large pen that has a screen front and a separate area that has a heat lamp. We added a small pond for water play as well. As the ducks got older we opened the fence so they could come and go during the day as they wished, always putting them in at night to keep safe from predators as my back yard backs up to a preserve with many different animals. I have always wondered when our ducks would be old enough to let them be free at night as well but haven't found a lot of info on the matter. Over the last month 2 have flown away and now, just today, I came home from shopping and the last 3 males were gone leaving 1 lone female, sitting by the walk out patio door. I got her in the pen for the night but feel very bad that she is now left alone! I live in MN and the whether is getting cold, snow is coming soon! Does anyone have any advice for what I should do about this? Is she in danger being the only duck left? Should I still let her out during the day, hoping she will too fly south or find another flock to join? Will she be ok out side under a heat lamp for winter if she stays?? A lot of questions but this is our first year raising ducks and I honestly thought they would have stayed together!
