Is there a guideline for ball python growth rate?

[JoeNapoli]

... 6 weeks ago the breeder told me he weighed around 100grams . Now he weighs 127 grams.
I am bot sure if this is too fast growth but I suspect I fed him slightly too big prey ...

So you are worried that an increase of 27 grams over a duration of 6 weeks is too much? I've seen hatchlings double in weight in that amount of time.

Are you raising a pet? health/longevity priority? relatively inexpensive BP and/or profit not priority? maybe you have no interest at all in breeding?

or

an expensive high-end morph, profit margin main priority?



Many morphs that cost thousands of dollars today will be worth only hundreds of dollars a few years from now. Breeders that invest in those hatchlings need to get them up to breeding size ASAP if they want to realize profits, or even break even. There's a lot of power-feeding going on; it may not be publicized, but it's being done.
