Question: asking about the housing  of duck and breed
Answer: recommended to housing 
ducks do not require elaborate houses. the house should be well ventilated, dry and rat proof. the roof may be of shed type, gable or half round. it may have solid or wire floors. the wire floors are not popular with breeders. under semi-intensive system the house should have easy access to outside run as the ducks prefer to be outdoors during the day time and even during winter or rains. generally the proportion of night shelter to outside run is 1/4:3/4. the run should gently slope away from the houses to provide drainage. normally a continuous water channel of size 50 cm wide and 15-20 cm. deep is constructed at the far end, on both sides, parallel to the night shelter, in the rearing or layer house.  breed --khaki campbell
