CHICKYN indicates whether the household owned chickens. In some cases, the question referred to other domestic fowl, as well; see Comparability. The complementary variable CHICKNUM reports the number of chickens owned by the household.
The information in CHICKYN is taken from the household record and applies to regular household residents, not temporary visitors. Researchers may wish to exclude visitors using the RESIDENT variable when women, children, or births are the unit of analysis, and using the HHRESIDENT variable when household members are the unit of analysis.
