It will take them a couple of weeks to sort everything out, and then all will be right with the world yet again, until the final group of young'uns is moved over in about another month! I'm equally stressed during these times. What Mom is OK watching her little one's get bullied!
In the meantime, the youngest batch had their area expanded and will allow them some extra freedom to stretch their wings, and mock fight on occasion. It sure is fun watching them grow up.
