I have a about 2 month old crested and i was wondering how old they are when you can sex them?

Or like when the males start getting their bulge.

if I recall correctly, they can be accurately sexed between 6-9 months old. However, if you have a good magnifying glass, you sometimes can pick out the femoral pores at a much younger age.

Usually you can't be 100% sure of their sex until they're about 20 grams. Some males tend to be late bloomers, and can "pop" up when your supposed female grows a bulge at the base of "her" tail.

I haven't gotten to try the magnifying glass method though
