@campingshaws, I throw my ducklings out at 2 weeks to an unheated coop. As long as they stay dry and out of the wind they can withstand down to freezing easy. Ducks are super tough
Thank you! The tractor was built for chickens and has a loft for shelter, but I really don't want scovies trying to manage that ramp. They're getting a house in March, so I'll just keep rigging them places.
