Feather plucking, is the nightmare of bird owners.
Why do birds self pluck, or pluck their partners or chicks, or everyone else in the flight with them?
I suppose there are as many reasons as there are birds, and they're not telling.
Some of the reasons, are boredom, dietary deficiencies, preening gone wrong, overcrowding, quarters too small, loneliness, stress, allergies, looking for nesting materials, frustration, aggression...... etc, etc, etc.....
I have a serial plucker in my Zebra/Society flight, who strikes periodically over night, leaving plucked birds, tail-less birds, bald birds. It's a real pain in the a...neck let me tell you.
With just the two of them (?) you could seperate them for a few weeks, giving his feathers a chance to grow back (which they will fairly quickly). Hopefully with a little break, she'll forget about trying to pull all of his hair out .
Another thing I could recommend, would be changing the cage around a bit, adding some fake plants, swings, maybe a mirror. Hang some spray millet from the roof of the cage, making it a bit of a challange for them. Daily baths. Make sure they have cuttle bone available, and a source of protein in their diet, along with greens. Sunlight, or full spectrum lighting. A foraging box is great too.
Goodluck.
