So my mix layer chicks are about 3 weeks old, and starting to outgrow their rubbermaid brooder box. We are currently working on remodeling a rabbit hutch for them. I have noticed that they fly up and try to hit the heat light a lot. I will still need to keep a heat lamp on them in their new home. Will they continue to fly at the light even in a bigger area? Should I just keep the light on the outside of the wire (not in with them)? Have you ever had a chick/s try to fly at the light? Why do they do it?
