My pijs live out in the insulated garage and so far seem to be doing just fine. But it can get brutally cold here... -50F windchills in Jan and Feb. There's no drafts in the garage and I offer them sunflower seed and peanuts as a high-fat supplement to help stay warm. They also have a nest box full of hay (that they never seem to use, LOL). I'm wondering if I could offer some sort of heat source for them for the coldest parts of winter? Heat lamps are nice but they just seem so dangerous, especially in a garage full of lumber and hay. They make those electric heating pads for doghouses, or those microwaveable things that don't use electricity? Would a pigeon use any of these things? Any and all input on how to keep my pijs warm and happy this winter would be great! If it matters, they are on the kind of young side.. they're about 5 months old now. Full feathered though.
