There is a domestic hybrid duck at the lake that I'm not sure what the breed is, but I think she has bantam appleyard or snowy mallard in her (she is around the size of a wild mallard). Her exclusive mate is a snowy mallard. She had ducklings last year, two of which survived and look mostly mallard with some "frost" on the wings just like dad (but not as red as he is).
This year, she had 7, but eventually got down to 2 after two weeks. One of the two was weak and the family couldn't forage much as the one duckling had to rest all the time even after a few minutes of activity. That duckling died two weeks ago and now the remaining duckling is very active and eating a lot for long periods of time.
He is now about 5 weeks old and still looks like a 2 week old (at 2 weeks old, he wasn't much bigger than a hatchling). Other mallard ducklings only a few days older than him are nearly fully feathered and twice as large.
I didn't see how fast her last two ducklings grew last year as they were kept away from where people can go. But they are now as large as the father who is slightly larger than than mom. I think I first saw them after 2 or 3 months after I saw them as day-olds.
Do bantam breeds grow slower?
Also, he swims around with his eyes closed a lot. Both him and the other duckling both did that nearly all the time they were swimming. I noticed their mom also closes her eyes a lot more than the other ducks.
Here he is as of today. He will be 5 weeks old on Tuesday and has very few feathers, mostly on his belly and near his tail.
