So far, no bald spots, but she's starting to look scruffy.
Rabbits shed every three months.
Every alternate time they'll have a light shedding that may not be very noticeable. Next they'll have a heavy molt that you will not be able to escape. Rabbits will shed in different ways. Some will take a couple of weeks or more to lose their old coat of hair. You can often remove a large portion of the hair by just pulling it out with your hand.
