nope. he meant that when u breed with such snakes u have a higher chance to produce the 1 in 16 morphs- because big snake- more eggs.
if its genetic- idk.
but the guy who sells em here in germany flys every year to africa and hand picks his imports. only babies that at birth weight more than 100g are sold as giants.
we get monthly prospects from him but the giants are long out of the list- i didnt knew he sells em still.
the last time i saw it was 2007 (in this prospects).
hes a good guy and people trust him- so i dont think that he want to screw someone with these.
and he has some really big girls there. the biggest is andy lewe- 5400g but its over 10 years old.
