Numerous credible sources on this subject can be found on the Internet, many from leading agricultural institutions, including the University of Arkansas, Mississippi State University, the University of California-Davis and Ithaca College. They offer easy-to-understand information on sexing newborn chicks including charts and tables with color illustrations for popular breed-specific identification. Yet, sexing young chicks is a difficult task with most breeds. Odds increase for determining the sex correctly when secondary sex characteristics arise after they are several weeks old.
