By Bible I am guessing you mean GM's more complete chondro?
You will do well with the species if you follow the advice in GM's book.
As for your question about metabolism, chondros are not all the different from other snakes.
Babies should be fed every 5 to 7 days, yearling's every 7 to 10,
adults 10 to 14.
I always advise people to error on the small side when picking your feeder size.
You can always feed again sooner or feed a second feeder but you can not take back any damage done by a meal that was too large.
If you are just going to buy established US CBB babies save your self some time and buy or build a rack.
As Meg said you WILL end up with more than one.
And instead of setting up multiple cages a rack with get you going and keep the animals caged for just over a year.
Good luck and don't be afraid to ask questions!
One last thing if you set up a tub rack set it up and work with it prior to adding the animal.
This will allow you too work out you thermostat probe placement, misting amounts, ventilation and tub drying times.
Do yourself a favor and skip the substrate all together.
