Molting hen

[JKGooch]

I have a year old hen going through her first molt, and she has started acting aggressively to the rest of the flock. She will jump on the other girls' backs and bite their necks. She will peck and sometimes draw blood. She never acted this way before. Is this normal?

They can get cranky during molt...do you have plenty of space for how many birds you have? What and how exactly are you feeding?
