Humans mostly obtain animal-based proteins through chicken meat and eggs since there are no societal taboos. The modern chicken is most effective for producing affordable and high-quality protein because of ongoing genetic selection. It is the first bird to have its genome sequenced hence called as golden genome, paving the path for other avian species to get scientific break-throughs. In order to minimize the demand and supply gap for ever increasing human population and boosting productivity, integration of different omics is necessary to understand interplay of different biomolecules and from that insights can be drawn for genetic improvement through selection or alter and introduce new traits through gene editing. The chicken is also a perfect model for studies in development and evolution, as well as for use in agriculture and medicine, owing to a variety of traits in its genome and biology. Hence in this review, integration of omics approaches, such as genomics, transcriptomics, epigenomics, proteomics, metabolomics, metagenomics, and lipidomics, their current status is highlighted.
