Does this behaviour sound normal for a 6 year old

My 6 year old daughter pulls her eye lashes out when shes stressed out or angry, lashes out having tantrums daily over pretty much anything. Screams for hours on end. Is a good talker and is great at school but behind with reading but no behaviour issues. When she is on her own she is excellent but around her siblings they fight a lot, more than what feels normal. Just screams and tells everyone she hates them and sits there ripping her eyelashes out. I have to sit there and be screamed at for like an hour before she will finally just snap out of it, apologise and act normal again
