Hi Bee-Liners, For the winter, some Quebec beekeepers leave their hives outside in a wooden box. Some others have expensive insulated and heated barns... Some very well insulated houses were made and are still made of straw bales. I am thinking to build a straw bale tunnel of the length of a trailer (12m, 40') and leave the hives (6 per pallet) on the flatbed trailer I need to carry them for polination to minimize handling. Is it a good idea? With colds reaching -30C (-20F) would It be better to have heating? Ventilation? When beekepers use pallets (6 hives, 3 each side) what is the orientation of the hives? Are'nt all hives supposed to have their entrance due south. Jean-Louis Adant (Quebec) Excuse my english.
