Hello,
First of all beardies shouldn't be housed together. Here's a link that shows some of the injuries that can come up:

Having babies hatch and taking care of them is very expensive. They eat like there's no tomorrow and you need bins, heat lamps, uvb lights. Notice the plural lol (I had some hatch in September and October).
You should probably also give your female some extra calcium because laying eggs takes a lot out of them. If you haven't already done so, you should probably read the breeding 101 thread.
I had my two, Kinky and Xena, together because I was misinformed. When puberty hit them Xena was younger than is wise for a female beardy to lay eggs. Fortunately she had grown quite a bit and it didn't harm her (visibly). She was 7 months old when she first laid eggs.
