Please help, I'm so confused

[beaubeaumont]

So I have two Hermans (thb), I had them since they were hatchlings and they were incubated to be female. They hatched August 2008 so they are 8 years old. Eggs have been laid! So I'm thinking one is male. One is smaller than the other, so I intially thought that was the male (now renamed by my son as James). However the larger one (Daisy) has a much longer tail, the small ones tail is almost non-existent. So then I thought the one with the long tail must be the male. I separated them, as the smaller keeps chasing the larger one and trying to bite her and mount her. And now the large one has laid another egg (the 4th egg in three days), so now I'm back to thinking the larger one with the longer tail must be the female after all? I'm really confused, anyone got any suggestions? Not sure how to post pictures
