I have an area where I want to build my coop but it is rather shady. Actually every place I have to put the coop is very shady so if I need direct sunlight I'll need to cut down some trees. I read that egg production is tightly associated with how much light they get. I'm wondering if filtered sunlight ( ie: thru the trees ) is ok or do they need direct sun? Should I also put a light on a timer in the coop itself? Thanks in advance.
