Duck pulling feathers out of other ducks tail

[myoooniee]

I have two ducks, a male pekin and a female mallard, both 4-6 months old now. The drake has scoliosis and doesn't move around too much and the mallard sticks with him most of the time. I've noticed recently that the mallard has been picking at his tail feathers causing him to cry out and try and waddle away. I just found some blood on his tail just this morning.

I've been looking up things to see why this happens, but so far, all the info has been on drakes causing the problems, not the hens..Can anyone tell me why this is happening and a possible solution to it?

she’s probably bored, since her friend doesn’t move much and she doesn’t want to leave him
