I have been told to take them to a reptile show and find someone who works with frilleds sex them. How old do they need to be? I relize that being only about 4 months old they are still too young, but can they be sexed at a year, two years? Also, does any one that deals with frilleds go to any of the shows in Kansas City or St. Louis? Those would be the closets to me (and ST. Louis is a 6 hour drive).
