I will be getting a pair of Java green Peacocks in about a month, and I am almost finished building their enclosure. Java green peafowl cannot handle freezing temperatures and I must keep the coop above 35 degrees. I live in Wisconsin were it can get way below freezing in the winter, nights have gotten to -20 (maybe once or twice a winter). My shed will be fully insulated and heated, and that is where my question lies. What type of heater would be suggested? I will be using a heated perch, but that will not be enough to to warm the whole shed (it is 10'x12' with 8' walls). I thought about one of those oil radiators, but I am not sure if something better is out there. I am buying one of those outlets that turn on when the temp drops to 35 degrees and off at 45 degrees. Thanks!
