The brooder is in the garage. There is a window, and I keep the garage light on all day. When I go look in the brooder and use the phone’s flashlight to light things up inside, they all run to the feeder and start eating.
Everyone is attracted to light. You might want to hang a light over the feed, or at least a light near it. I use a full spectrum light bulb meant for plants. I also turn a light on during the day. I also have chicks in the garage. They need light to help their developing eyesight.
