My house has a central vacuum. The motor unit is in the garage. We'll since moving the chicks to the garage I only used it once and went outside and the poor things were huddled in the corner. The central vac motor is LOUD. But my floors have all kinds of muck and need to be cleaned. I can't move the brooder because well its huge. Do you think it will hurt them? I worry about giving them a heart attack. Once it started would they just get used to it? Or should I wait until hubby gets home and both of us carry the brooder outside while I vacuum?
