Ok, I'm obviously not a farm girl and new to raising chicks. My bf just found a mouse (not a large rat) in our bathroom next to the room we keep the brooder in. We have 9 chicks that are about 19 days old. Can a mouse hurt them? We will set traps, but we need to go buy some first and its midnight here. Our brooder has pretty high sides, it is 2 x 2 x 4 galvanized stock tank with chicken wire over the top of it, but it is next to a dresser. Should I be worried tonight?
