I have two 7 week old ducklings, they have been doing just fine outdoors during the day, but I bring them in at night. They are outgrowing their indoor set up and I wanted to know others thoughts are on an appropriate age to let them sleep outdoors in their predator proof enclosure with a bed. I live in southern California- lows tonight are 61. I have found other articles and discussions but the information varies and would love to have some well seasoned advice. Thanks!!
