I have 5, two week old chicks that are scratching like crazy in their box. We have a small house and their box is in the livingroom. I love listening to them during the day, but at night they seem loud and very busy. I have a red light on them for heat, and turn white light on during the day and off at night. But they don't seem to be settling down at night. They are scratching and peeping like mad late into the night. Is there a better way for me to tire them out during the day or something I can do so they will quiet down at night?
