Ducks are pecking at chickens

So my mallard duck who is about 4 months is pecking at my chickens, should I be concerned ?

Are they enclosed together? My ducks will grab a chicken if they get too close but mine are not enclosed in a pen together.

Chickens can cause serious harm to ducklings/ducks and ducks can cause serious harm to chickens, drakes by trying to mate with a chicken or just by holding one down and pulling out feathers. I would not keep them enclosed together when one or the other would not have a way of escape.

They're enclosed from 9 at night to 7 in the morning (with the Chickens) . I normally see the duck peck the chickens when they're outside but whenever I go to clean they're pen there's a good amount of feathers (wether that's from the chickens malting or fighting I don't know)

Pretty ducks. All the feathers you maybe seeing now is from molt my coop on the inside looks like some one plucked some chickens there are feathers everywhere. Are your chickens adults? Best way to find out if someone is being a bully is to sit out and watch them.

I have 2 grey birds (sorry im not sure what bread ) and they're 2 of the biggest out of them all. I recently bought 3 new chickens of my mate they're Rhode Island reds (they're not fully grown just yet ) and they're getting a hard time by the two grey chickens but I guess they're just establishing a pecking order.Then I have a beautiful solid white chicken who shows sign of aggression towards the new birds but hopefully that will blow over.

Whenever I'm in the yard I always see the ducks peck at the chickens and not the other way round but then again when they're all locked up at night it could be a whole different story.

There's a Sunday market I normally go to so I might buy a few more ducks to even out the numbers, I'll keep you informed
