I have been going back and forth with this question as well. I just got my 4 hens and have them in the coop. I bought pullets cause I didn't want to start with the chicks my first time around. So, I was told by Southern States it will probably be two weeks before my hens start to lay. I was planning on adding the light to the coop. I actually have them in a temporary coop in my feed room of my horse barn. But, just to make sure I understand, if there is no artificial light, I will still get a eggs correct? I am not selling or producing eggs for a business or anything. Just want to have fresh eggs for the family. But, I would like to have a fried egg for breakfast sometime this winter. The feed room they are in does have a window facing west so they do get sun. So, If let nature take its course, I will get eggs just not that many correct?
