Young indigos are the most prone to bite. That said..I have never
been bitten by a eastern indigo other than in a feeding responce
which can happen when i'm careless. I keep them in fairly small
enclosures for the first year or so, make sure they have a hide,
water available at all times and please dont overheat them.
I keep my youngsters at low to mid 70s at night to high 70s in
the day. Hope that helps. Also..If this PA breeder guy is talking about eastern indigos then he doesn't know what hes talking about.
