Hey there, this is my first time raising chicks. They are about to turn two weeks old and are living in one of my bathtubs. I was hoping to keep them in here for another couple weeks before moving them to a different room, because the bathroom is warmer. They do also have a brooder plate. There's no window in this bathroom though so they aren't getting any natural light. Is that going to be a problem? I have a happy light I could leave on for a while if that would help.
