I had one doe who was very much the same, before I got her she would pull fur every time another rabbit was kindling, although she'd never been bred.
I also had a doe that pulled fur on compulsion. She would eat it mostly, and I had to constantly watch her for hairball, though somehow she never did get any. Her dewlap was constantly naked, litter or no. I was just selling her kits since she was a dwarf and they were too small to have any meat value, but that got tricky when she started pulling their fur too. Leaving any past weaning age was a disaster, although she was a wonderful mom otherwise.
I had one black eight week old doe I was supposed to meet someone after work to sell, and during work momma decided to give the little doe a haircut. She plucked between her eyes on her forehead and up to her ears completely bald. I was so happy the buyer was understanding and still wanted the rabbit when I called her and explained the situation. I was afraid she might suspect fur mites or mange! That doe is now in happy retirement at my mom's house as a pet. Oddly enough she's stopped self plucking too, though I never could relate it to her being bred or having kits.
