You don't have to be scared, just be aware. So many new cham keepers have no idea their females even produce infertile eggs that by the time it's obvious she is beyond help. Or they've kept the pair together and the female is so stressed by constant contact with the male she is guaranteed to have problems. It is a myth that females must be bred to avoid egg binding. Many keepers have females that lay their clutches routinely with no trouble. First, the heel spurs should be obvious very soon if not now, if it is male.
If you do have a female don't panic! Much of the egg binding problems come from overfeeding, stress, ignorance, and poor supplementation, so you can avoid these things.
While she is a baby you can feed as much as she wants just as you would a male. Don't attempt to breed her before she's a year old as there is more chance she is not physically mature enough internally to produce and lay eggs without trouble. Females draw so much off their own calcium reserves when producing eggs that you want her skeletal structure etc. to be in prime condition. When her growth rate slows down after 6-8 months you should not feed her as much. Go to every other day and watch her weight. Start weighing her so you have an idea when she slows growth or when she starts egg production and becomes gravid. Some unmated females kept alone without socially interacting (seeing him etc) with a male never start laying.
Here are some good sites with info articles on females, egg production and laying and how to get ready for it. If you know ahead of time chances are she'll be just fine.
