I have gotten every one of my BCIs as babies and not a single one was nippy - then or now. Sure, it can happen, but it is most definitely NOT a tendancy. And if it does happen, they do tame down very readily with gentle handling. So I wouldn't worry about that at all.
I just picked up my first Dumerils yesterday.And I am very happy with her - she is incredibly sweet and docile and already likes to be held. But so did my 3 BCIs! Even my BCOs (Argentines) like to be handled and I have no worries at all reaching in their tubs.
You will be extremely happy with a Dumerils, Hog Island, or male BCI - very happy indeed!
I would suggest going to a good reptile expo nearby with an open mind. Don't have one or the other as a preference. See what you like and see what breeder you like working with and talking to. See which snake "speaks" to you. I did this when I was picking out my first boa. I handled a couple of Dumerils and several BCIs. Found a beautiful little hypo female at Special K Reptiles' table. Tim was great to talk to - the most patient and helpful of anyone I'd spoken to that day. I bought that little girl and have never been sorry - it was a fabulous experience and I got a terrific snake!
Just be aware, pet or not, boas are addictive - bet you can't have just one!!!![]()
