    VI.—DISEASES OF POULTRY. The commonest causes of mortality amongst poultry are Spiro- chaetosis and fowl plague. The former disease affects fowls, turkeys and pigeons and is transmitted by the fowl tick ( Argas persicas). As the adult ticks hide in crevices in the fowl house through the day and only come out at night to suck blood, their attacks can be prevented by suspending the perches from the roof of the fowl-house by means ot wires and dressing these wires at frequent intervals with tar. Broody hens may be protected from ticks by placing them in a box supported on legs the feet of which are immersed in dishes containing paraffin oil or a solution of disinfectant. In addition to the above precautions the fowl-house should be thoroughly sprayed once a week with strong paraffin and soap emulsion .
