Scovies rock! I keep mine with wings clipped so they don't roost on the roof of their shelter in their pen anymore (it's about waist height stable style) but I change their bedding where they sleep at night because they are so messy. I don't have aggression issues unless hand feeding meal worms, they can get a bit snappy but think that's more because they want them so badly and not from aggression. I have 3 girlies and they started laying August 3rd and to date I have had on average 3 eggs a day with one girl taking 3 days off but she has started up again. We don't eat the eggs as quickly as they are being laid, but we try do alot of baking. They are quiet, great foragers and weeders (in the drought that's the only thing that seems to have survived!) They dont spend as much time in the water as other ducks so my bio filter system in the bath tub I have set up in their pen is not under as much strain as it should be. The only disadvantage I have is their claws, they can be quite hectic, so I learnt to clip wings at night while they are passive to save my arms. Oh and another disadvantage is that indefinitely don't have enough of them!
