Definitely separate your Beardies. It was a sweet idea to want a companion for your pet, but Beardies aren't like people. They don't need other Beardies to be happy. All they need is proper lighting and food, and daily interaction with you, their owner. As another member of this forum once said, Beardies are solitary animals, and each one deserves his own domain.
The previous owners of the Beardies I have now bought them together at a pet store as babies, and kept them together because they were "so cute" and "got along really well together". Well, surprise surprise, Draco (my male rescue) has a tail nip, and Sunny (my female rescue) was gravid when I adopted her, even though she was only just over a year old, and even then, Draco kept head-bobbing at her and kicking her out of all the nice basking spots.
Since I've separated the, each dragon has become a lot calmer, and each now has free range of their terrariums, as well as first dibs on food and basking spots. They really aren't meant to be housed together unless you want eggs, and I don't know why anyone would voluntarily go through that process unless they are fully committed to spending hours and hours online researching breeding info and hundreds of dollars raising babies.
Trust me, your Beardies will be much happier in their own space, and you don't want to put your female through the stress of laying eggs unless you've fully researched the risks, costs, and possible health risks to your Beardie, and even then, they should be kept in separate cages at all times other than when you're planning on having them breed, before which you need to put them through a period of brumation, vitamin supplements, etc. It's not a process I would recommend unless you're completely prepared.
Good luck, and enjoy your new Beardie!
PS. Just in case your female has already been impregnated, you may want to look into extra calcium supplements. All you need now would be an early case of MBD due to low levels of calcium during egg formation.
