Looking for advice regarding daylight requirements/run access for my new flock of 4 (still in an indoor brooder). I'm not an early riser, and it's likely that my coop door won't be opened until 8 a.m. many days. Should I add a light on a timer in the coop so the hens can wake up earlier than I do? I'm not prepared to spend money on an automatic door opener at this time. They do have a window in the coop but it is fairly dark inside until the sun has risen above the tree line.
