Ok, the real way to know ur bps age is to have hatched it itself or the person who did hatch it tell u about it.
The bed place to get feeders IMO is a local breeder of snakes or just rodents. My snake breeder also breeds rodents, so it's easy for me to get a new snake and then get a bunch of rodents Ali g with it. Try posting on Craig's list to see if you can find someone who locally breeds rodents.
Last answer a bought weight, every bp is different, heck I'll go as far as to say every snake is different. I would say a baby like that should be anywhere from 95-115 grams as my 1/2 month old was a little over 100. But, to be honest, it could weigh pretty much anywhere around that, give or take a few grams. As long as it doesn't have a "triangular shaped body" it's healthy, and babies may appear to have that shape but once they start to fatten up it should go away!!!
