A reduced-weight poultry cage is used in conjunction with a reduced-weight trailer to transport live poultry for maximizing the poundage of poultry being transported while reducing the number of trips and fuel expenses. The poultry cage includes a combination of aluminum and plastic elements that reduce cage weight, provide for nesting of cages in stacks as well as easy replacement of failed parts. Furthermore, a drop-deck aluminum trailer with a reduced floor and guide rail alignment stops allows for a durable yet lightweight trailer that can haul a plurality of stacks of these poultry cages, thereby maximizing cubic feet availability while being compliant with various road and bridge laws.
