My basic chicken coop plans have been ever evolving because of my continued research. I think i have as much figured out as i need to. I do have one last thing that i'm not sure about. The basic plan i started with and modified to suite my needs has a large skylight in the roof covering a third of it in the center. My question is, Is a skylight really needed?" I understand light can be manipulated to get the hens to lay at off times, but is light that important in the coop? So before all you wonderful people answer my questions let me just fill you in on a bit of info. i live in southern arkansas. We have some pretty hot summers, and the winters can get a bit chilly (nothing compared to illinois). The roof will already have ventilation going from back to front and i'm going to add additional windows with wire for vents also. Chickens being very productive in the wintertime is not a concern to me and my wife since we will be the only ones eating the eggs. Thanks for you thoughts and if you have any more questions throw them my way.
