For those of you who have purchased and used one - do you like them? If so, where online did you purchase it, and what brand did you buy? I see most of you mount them about a foot above the bedding which is what I would do. I'm measuring my coop today and after I hear from you guys and your recomendations I will order one. Safety is a major concern. We have brand new wiring in the coop now, so we are ready to roll. Thanks and Happy New Year!
