Rural Gardening: Aggressive hen used to be so sweet?, 1 by Heavinscent

So what happened? Nothing seems to have changed but almost overnight she has started fluffing up her feathers, attacking(not just peckng) and flogging like a roo. Im really confused she used to be the first to hop up in my lap... Now I have to try to stay away from her for my visits to the others in the group. She is a 5 month old bantam blue Cochin.
Has anyone experienced this and is there a way to bring her back?
Thank you!
