I always raise mine in large dog crates, they are fully in closed. The one I am using now is wire and lined with a plastic hardware cloth. In the beginning I have the light on the inside as they age its on top. It even keeps my cats out. If needed for warmth I cover all or part of it. Mine were flying/flapping around, young also. They are healthy and happy. You are doing good. My first set of bantams were crated in my dog room with my dogs and it took my husband 2 weeks to know they were there. HA!
