Welcome to BYC!
If she is molting, you will not only see feathers everywhere, but you should see some pin feathers coming in behind the neck and around the head. Usually they start a molt at the head. And generally with molting, they don't become aggressive, but shy and timid. So something else maybe going on here. Try to get a handle on egg eating as this will become a habit that you will never break. Put curtains over your nest boxes, and keep a fake egg in each box always. These hard eggs will help to discourage them from eating the real ones if the birds think the real ones are as hard as the fake ones. The darkened boxes will also help to deter the egg eating as well.
But it never hurts to add more protein to a chickens diet with some cooked meat...ground beef or ground turkey a couple times a week can do wonders for molting birds.
