Hi, I have a small coop about 4x6x3 feet which sits on top of the same size run. I would like to give the chickens some supplemental light so that they would lay, which they also need to be able to see inside, now that I have to close the door/window due to cold. This is their first winter, and they have been laying for about 5-6 months. I have this bulb that is warm white light 14w CFL =60w, also 2700K, and 900 lumens. Is this the right kind of light? Thank you.
