Anyone know why my duck raises her feathers like this when people go near her?

My khaki Campbell (her name is Jem) is doing this and she did it last year to.
When I notice Jem raising her feathers and quacking almost like she's broody, she does it mostly in the morning when I let them out of the coop and when I feed them.
I don't really notice it any other time.

My Muscovy female does this and I don't know the exact reason either. It seems like mine does it when she is annoyed by my SO following her around the yard. She has only done it to me when I was trying to round her up to go into the run during mid-day and she doesn't like that. Unfortunately, sometimes we have to make trips to the store during the day and I won't leave them out unattended so it's a necessary evil occasionally.

Edit: she goes in at night excitedly so no problems with being put up or the run/house area. It's just when she prefers to be outside free ranging.

Mine does this at all times of the day, any time anyone walks near her, she doesn’t quack or run when this happens, just stands there and fluffs, she quacks when a raven flies over but doesn’t fluff up. She only seems to fluff when we people are around

I was about to ask the same thing. My broody welsh harlequins do this and it started when they went broody.

How often do your harlequins go broody?
