one thing is for sure:
these african import hatchlings are the cheapest BP possible, since they go for around 7 dollars per piece in africa. if you place a typical order like for example 500, price may be even lower.
But you wont even know for sure if its a wild caught. they have these trading cooperatives where people bring their hatchlings for cash, and they get sorted and inspected and then combined into large shipments. this is also where the hunt for dinkers and new genes begins, people with money can come and pick out dinkers, also anything unusual gets set aside.
anyway the people that come to sell their snakes may be trappers, but most will catch gravid females and hatch out the babies and then let the female go and sell the hatchlings. then there also are farm breeders that keep BPs in a sort of semi-wild state, and real breeders bring their normals and low-quality morphs there.
most of what is considered wild caught is in fact captive hatched, meaning they caught a gravid female and kept the eggs and released the female. much will also be farm bred, where they keep semi-wild colonies of BPs in large enclosures. Real wild caught is rare. So the overwhelming majority will be in human care from the day they hatch.
honestly i think the only real differences are the price and the amount of parasites. these hatchlings may have been through a lot, the only advantage is an economic one: its a low price, high quantity, high reliability source of normal hatchling BPs of unknown genetics. perfect for big traders and big chains. When you want to order 1000 normal hatchlings, the africa connection will get the deal because even the biggest breeders in europe or the USA will have trouble with it.
