MC is a wizard, and as a young child still coming into her powers, she accidentally magically kills some animals in front of her mother. Wizards are not looked kindly upon by this society, so realizing her daughter is one, and seeing the destructive nature of her powers, causes the mother to have a mental breakdown and abandon her family and the army, never to be seen or heard from again.
My problem is, what sort of animals might they be?
They definitely need to be domesticated, not wild. I had originally thought of chickens, but then I wasn't sure if camp followers would be transporting chickens (although chickens would provide eggs...).
I've tried searching various reenactment blogs and articles but I can't find anything about camp followers having animals with them, or if that was even permissable.
