I love the two Ecoglows I have. I have the larger ones and they work great. Less electricity used and the chicks love it. I do have a light on during the day so the chicks do have a light cycle. I find with the Ecoglow I can turn the light off at night and the chicks don't freak out. Unlike a heat lamp, there is always a light on. That first night without a light freaks them out. With the Ecoglow I turn the light off on their first night and no problems at all. Well worth buying a few if you plan to have chicks at least once a year.
