Help i dont know how to stop this

[Shazwahh]

I have a special needs chicken that's recovering from a fox attack (see last post) shes been around our ducks since the attack no issues now all of a sudden we have ducks bullying her and biting her comb and stuff. No idea why this has started but I need it to stop. They are in an open yard thats about half an acre so it's not a space issue
They are pekin ducks if that makes any difference and not laying yet only a couple weeks until that starts

Its their instinct. I had a special needs duck. He lived inside the screened rear porch so that the other ducks and he could see each other and "talk to" eachother.. The flock came over as soon as the special needs duck called, and hung around when they were not foraging. But I could not leave him outside with them, as they would attack him. You will have to separate your chicken from the ducks.
