Male.....or Female?

Sexing
Bearded Dragons are somewhat difficult to sex, but there are ways.  First off, you can't tell from the size of the head or the size of the body.  The Bearded Dragon I saw with the largest of both was a proud mother, not the male that those attributes supposedly signal.  It is also hard to tell before around 6 months of age.  Not impossible, but hard.  Here is what you are looking for:
a) Femoral pores.  This is on the left picture.  While both sexes have these, the male has much larger ones.  The picture shows a male.
b) bumps around the vent area.  One bump is female, two bumps is a male.
