This 6 yr. old female normal is only 28" long. I don't have a scale yet, but she looks to be the same size as most pictures of 1 year olds.
Couple of questions I have:
I would start feeding "her" a small rat (4 weeks old) every 7 days1. Should I expect to be able to get her to feed much more often, say every 7-14 days?
If "she" is 28 inches long and really 6 years old that's pretty much it, while BP grow throughout their entire life the main growth is done between the first 3 years.2. After only growing so little, would I expect her to grow much more if I can get her to eat more?
I seriously would not see a point in breeding such a small animal does not mean it would be impossible however not something I personally would do.3. Would you expect that she'll be able to breed, or would there possibly be some problems with the age/size that have been caused?
Now as you noticed I use "her" however the first thing that would be in order would be for you to re-sex the animal or have a confirmation by someone else, given the size and the age even if not fed appropriately 28 inches would be VERY small for a 6 year old female, however for a male it would make more sense.
