I have 2 swede ducklings (I think-- the girl has a pouf on the back of her head?), and will prolly be getting 2 more this weekend after mother-in-law's church's Easter egg hunt (they want duckies and chickies for the children to see-- and I get to take them home). What sort of houseing will they need? is a lean-to type shelter sufficient, or do they need something more? I'm not too concerned about preditors-- we've not had many, they will be inside a fence, and we have a good "chicken dog"
