HC Deb 03 March 1960 vol 618 c157W
81. Mr. Willey

asked the Minister of Agriculture, Fisheries and Food how far overcrowding in broiler houses has affected the spread of fowl pest.

Mr. Hare

When fowl pest breaks out on premises where large numbers of young birds are kept intensively, the disease may spread widely in the flock before being discovered. The greater the number of diseased birds the greater the risk of further spread.
