We are VERY new to the chicken world - I apologize is this is being posted in the wrong section. We have had a light on for them 24 hrs a day since we got them at a week old. They are approximately 10 weeks old right now. Last night when we came home - we realized the bulb had blown and they were sitting in the dark. My question is should the light still be on all the time? Do they need to be in the dark at some point? I was just curious because they were huddled up in the corner when we went out to change the bulb - like they were scared of the dark!!! I have a timer and could set it for whatever is needed - just not sure what to do!!!
