Do you have a link to a solar light a with timer?I have put together a few coops this year- I would def add more windows and natural light to mine - I also would really enjoy the ease of an occasional light when needed - I have added some solar lighting to the coops with no elecrticity - I dont like it as well as I do the electrical ones but it works. I have a timer set for a light to come on for 2 hours into the night so they can get roosted easily - as my little ones wait til its too late and were sleeping on the floor of coops
