Hi,
We keep two bearded dragons in the same cage.
We didn't know their sex, so we asked a woman
who works at the petshop we often go to.
She told us that they are both females.
But from what I've read, males have bigger heads, right?
and one of them does seem to have a bigger head than the other one.
Also, the other one never laid eggs.
(Am I just getting confused by these small things?)
They're around the same age and we've been feeding them the same thing.
About two months ago, one of them laid her first clutch of eggs.
We were totally not aware of it and found it a little late.
I remember there were around 13 of them...
They were all indented and dried, because they were under the
spot light area.
The same beardie's pregnant again, I can see the marble sort of bumps under her belly.
She no longer wants mealworms, but loves veggies and water.
I thought the eggs weren't fertile, because they're both females.
But I'm confused now...
...the two beardies are behaving weird.
They're nodding their heads,
The one that's not pregnant, is very aggressive and mean 
to the other one.
(It once bit the other one.. 
)
The pregnant one seems to be looking for an egg laying site.
She also looks very nervous and jumpy.
We keep them in a big tank, but there's nowhere for her to dig deep.
So I put a medium sized food container with some moist soil in it.
I guess the eggs aren't fertile, but will I know if they are or not when she lays them?
Okay, this was kinda long..so let me summerize.
-I'm not sure if both of them are females...
(any clear differences between male and females?)
-Females do lay infertile eggs by themselves right?
-How would I know if the eggs are fertile of not when she lays them?
-If one female is pregnant, is there a reason for the other female to be aggressive and mean? ..Like biting??
Alright! It's over now!!This is the end to your reading!!
Now...replying time!!!
