Chicken is one of the major livestock, especially for supplying proteins to human and the Korean native chicken (KNC) has been documented since approximately 2,000 years ago (Seo et al., 2013;Seo et al., 2015). But, due to their poor commercial performance, Korean native chicken breeds almost became extinct and the breeds that existed before the Korean War (1950)(1951)(1952)(1953), are almost all extinct (Seo et al., 2013;Choi et al., 2015). After the Korean War, commercial native chicken companies maintained various independent breeds while continuing production and market distribution (Seo et al., 2018).
