To add on to what Cody said, females do not necessarily always have the urge to lay, either. It depends on their relationship with the budgie they're housed with and how well the owner can successfully throw off her hormonal patterns to avoid the situation to begin with. You do not have to house them separately unless it's obvious they keep trying to mate with each other despite your efforts to discourage it. However, you will have to be vigilant and keep an eye out for any egg-laying or anything so that you can toss the eggs before any life has formed, etc.

Personally a lot of this is up to the female in question. My girl is 10 and she has never been broody in her life. Of course, she never has access to any space or situation where she may become broody. On the other hand some other single females have to be constantly deterred from laying. It all depends on the individual hen. The best you can do is follow the information in the links above and always remain watchful and perceptive of your budgies' behavior~

To prepare for the potential situation that they could need to be housed separately (if they don't get along, if one of them begins to bully the other, or if they insist on mating) you should try and have a spare cage on hand just in case
