Nice, I live on the east side of Seattle. Definitely need at least three ducks, just in case - things happen and it's so sad to keep a lone duck. I also would advise you to think strongly about pekins and do plenty of research. As they are bred to be meat ducks and harvested at a young age they potentially have a lot of health needs, mostly due to being such a heavy breed. I've had three pekins, one I put down last year at two years old, after she became lame, and now one of the other ones is having a lot of difficulty walking. They are more prone to bumblefoot as well, due to their size. They eat way more and poop way more than my other ducks. They're personalities are nice, but you can get a smaller duck that looks similar in a Duclair or white layer. I suggest going as big as you can for space - space is nice for them and they need a large area that is protected from predators and the rain. They definitely need swimming water to be most happy - they're waterfowl and it's how they're designed! It keeps them clean and bug free to bathe multiple times a day, and is when they seem to be most joyful! I've used the plastic kiddie pools, which need to be scrubbed and frequently changed, and also have the heavy-duty black pre-formed pools. Be aware that if you don't have a lot of land ducks will be very hard on your grass. They need to have plenty of room to forage - that's what they live for, not being enclosed in a pen! Ducks take tons of time and energy - buyer beware!
