First off, they grow SO fast! They were nearly fully grown at one month - they lost all their yellow fuzziness, for sure! I had no idea ducks grew that fast - they are not true ducklings for long!But on the flip side, as they grew, their personalities came out! Who knew ducks could have such personalities - the two are so different in nature! Louise is a bit more of a mama's girl - she doesn't freak out if I pick her up and seems to enjoy being petted, once she settles down from being picked up
(she squirms a bit, before she realizes she's going to get spoiled). She was also the first to come eat treats out of my hand. Thelma is a little more guarded... will run (waddle) as fast as she can to keep from being picked up. But it's never fast enough. So when she is picked up, she kicks her little feed, and starts breathing heavy (purposely, like she's pissed). It's actually adorable, and just makes me want to pick her up more. 
And the interaction between them is quite interesting, too. I *think* Louise is the dominant one, most of the time. She, literally, will talk down to Thelma. But then I'll see Thelma, occasionally, push/prod Louise with her bill. Regardless, if they get separated, it's like you took away the other's heart! Loud quacking and panicked scurrying around. They are always side by side, even when they are 'running' from one corner of the yard to the other.
Thelma was my egg layer first, about 2 months earlier than I expected (started two months ago). But Louise was only about a week or so behind. And they are quite consistent layers, both in location (in their little hutch within their giant pen we built), and in timing. Every morning. Sometimes, one won't lay, which is normal. We'll see how it goes as we get into the winter. I've read different things on if they lay or not. 
Eric refuses the eat the eggs, though - not sure why. They taste similar to chicken eggs - maybe a tad richer, since the yolk is bigger. But I like them. I am keeping a few people at work supplied with them, as well. Might as well, since there is no way I can go through 14 eggs a week!
So if noting else, ducks are very much creatures of habit and routine. I love that, even though our backyard is not completely fenced-in, they never leave the back yard. They love their pool... but are hesitant to go to it if it's anywhere but in their pen or in the corner by the house. They quack loudly when I come home (especially if I take too long to come out of the garage). Kind of like a dog that gets excited. When I first let them out of their pen, they run/waddle across the yard, and try to 'take flight' as best they can... it's more like just a lot of wing flapping. 
Then they run back and jump in the pool or, if the pool's not out, they will settle into their routine of foraging around the yard, starting by the holly bushes by the garage, almost every time starting in the same place and following the same route.
They love berries. All berries, so far. Strawberries, blackberries, blueberries... and grapes. They will attack me over grapes. But even some basic romaine lettuce is a treat for them. They come running to the backdoor as soon as they hear the fridge door open/close(usually we just have the screen door pulled closed). They can be clear across the yard when they hear it - good ears! They just assume they're getting treats. And did you know that ducks do yoga??? It's really just their typical stretching routine, but some of it looks like some yoga poses I've done.
All in all, it's been a fun six months! I never thought I'd own ducks, let alone any sort of farm animal. But they're a lot of fun, and pretty easy to take care of! I'm a little nervous about their first winter - everything I've read says, 'they have built in down coats, so they can handle it.' But I still worry - those same stories talk about their little feet getting cold. But they do love the slightly cooler temps we're getting now. Throw some rain in the mix and they're happy as, well, ducks! Rainy days equal quality mud time for them - I now understand the term 'muddy duck', as well.Ducks! Who knew?!?
