My drake is plucking at one of the hens.. what to do?

[Stoney Meadow Maple]

My injured Rouen has the green light to sleep in the duck house, she’s been with the rest most days for a few weeks, no issues. Today after returning from the vet the drake is plucking at her face when she goes to drink. And then he did it in the duck house tonight while she wasn’t drinking. I just brought her in rather than deal with it. I wondered if separating him for a night might help, or if it’s just normal. It’s not really violent, just doesn’t look really friendly.

As long a neither is being hurt, I'd leave them together.
