Duckling has shallow breaths, is this normal?

[bianca1]

My ducklings are two weeks old, and one duck seems to have started breathing more quickly. I’ve never raised ducklings before, so i’m not sure if this is normal, or if I am worrying for nothing. They have access to water they can dunk their head in, and their nostrils are clear. I fully change their bedding every morning, and add more throughout the day as they make a mess. The duckling i’m worried out is on the left in the linked video. Any advice would be very appreciated!!

They are precious ❤ I don’t think
It’s anything to worry about they don’t seem to be showing any distress.
