The chicks are in the basement in a brooder my husband built. It's quite large so for now they are sectioned off so they stay warm. The problem is the basement has no windows where they are and they aren't getting any natural light! Is this a problem? If so how do I fix it without having to take apart the brooder he built and relocating it. They seem fine. Today, I noticed they are sleeping more than normal, but they also seem less stressed and used to their new home so I think it's just them settling in. Thanks for any help!
