Hi sunburn Yes I do let them free range but I like to lock them up at night. With 16 ducks I thought the area of lock up may be too small when the ducklings get bigger. The big ducks seem to go out but the ducklings just hang around in the chook house and straw yard at the moment. I leave the door open for them to leave but maybe they are still a bit timid. The long grass around there may be putting them off. It is hilarious watching them catch flies and bugs. Some of the ducklings just lay there and wait and then jump up and snapola!!
