Ah wow! I didn't realize. This is the 1st day that the light is on, so it should be 4 hours early in the morning? Or when should the light come on, or go off? Two hours early and two hours at night? Maybe just 3 hours in the morning? This is my first time having a light to continue egg laying..
That's ok, you didn't know. You can start the light early in the morning and even have it turn off once full day light starts if you have enough windows/ natural light in the coop. You'll get the hang of it!
