Oh, I doubt it. If everyone is getting along and the scene is tranquil, they'll be just fine. Of course, once the older girls begin to lay, they'll be a bit more pushy about certain things.
Cant wait for them to lay 2 of the light sussex's are very "fat" looking - maybe they are older. Im still unaware who is roo/hen, the light one in the last pic closest to camera i am near 100% is a roo, very outgoing and bossy - love to stand up straight with the chest out too lol
