Actually Adrian Hemens was the ORIGINAL breeder of the Australian Native line. While he did produce a mixed clutch 3 or 4 years ago these were NEVER sold as natives nor did they look like natives. He has bred PURE natives every year since 2005 and this year produced the very first F2 babies. So Hemens line DOES mean pure aussie. Before waterrat states that Hemens lines are not pure he should remember that ALL his original animals came from Hemens and therefore he is casting doubt on his own snakes.
Never, ever have I seen native hatchlings changing colour before 8 months of age.
Hemens line does not necessarily mean pure ausie line, he bred natives X PNG some years ago. I think it's a common knowledge.
I am not saying the ad is misleading but it's absolutely extraordinary for 3-4 months old natives to go green and to be big enough to feed on small rats.
