Khaki Campbell ducks seldom hatch out others' young; however, in very communal situations do hatch large broods together. Most brooding behavior has been sacrificed in exchange for prolific egg laying ability in this breed. The ducks, when raised by hand, are not usually defensive of their eggs or nests, making collection of eggs very easy. Mechanical incubators or broody chickens are used to hatch out Khaki Campbell ducklings when ducks are not present in the process. Incubation takes approximately 23 to 28 days for a Khaki Campbell duckling to hatch and eggs need to be inspected for ducklings that have not emerged
History of Rouen the First World War, the British used Rouen as a supply base and there were many military hospitals. Rouen was heavily damaged during World War II – approximately 45% of the city was destroyed. In June 1940, the area between the Rouen Cathedral and the Seine river burned for 48 hours as the Nazis did not allow firemen access to the fire. Other areas were destroyed between March and August 1944, just before and during the Battle of Normandy, which ended on the left bank of the Seine with the destruction of several regiments belonging to the German 7th Army.
