Ducks are so much easier. They don't peck each other to death. In fact, they won't fight at all if you raise them together and only keep one male past maturity. Even if you break these rules that won't fight much. They can handle colder weather (they don't need a coop in most of the US, just a predator-proof run). The two big downsides are they they poop a huge amount and they are hard to pluck.
