I have a frizzle who has gone broody on me without having eggs under her. Not sure if this is a normal behavior. When I've tried to move her to check under her for the last week she has had no eggs but has become very aggressive and I would say is biting...as opposed to pecking at me. ie...it is not a quick warning peck, it's a full on, grab hold and don't let go for a few moments bite. Just want to know if this is normal. Thanks for your help!
