Earthworm - 1/3/2012 21:53 Depends on how it is built. Winter time hard to get pigs to go against cold air. I didn't know building type could make it warm enough outside to make the pigs load better during the winter. If that is the case I'd hate to load out of a tunnel because I think they load terrible out of our curtain barns when it is cold and windy outside. If there is ventilation there will be air coming in the door. |
