I'm wondering if I need to have actual windows in the coop as well as all the ventilation up by the roof. One main window I wanted to add will be on the south west side.. so it will be the warmest side in the afternoons. Good in winter, bad in summer. But, I'm also planning on putting shutters on it... if I did that, it should be fine right? So I can close the shutters in the afternoon in the summers to prevent it from getting too hot... and keep them open in the winter to allow sun inside the coop. Am I on the right track?? I had also asked in another thread of mine about pop door placement in relation to the nesting boxes... will it hurt anything to put the pop door on the opposite wall of the coop, right across from the nesting boxes?? I didn't figure it would hurt anything in the summer, but what about in cold weather?
