I have a female Bredli also born in January (I've had her since late Feb) and she is the most gorgeous, placid snake I have ever seen. The only time she ever strikes is more as a warning than intention to bite me, she will just swing her head around with mouth open but not actually make contact. And she has only ever done this a few times anyway, it just makes her cuter! I only handle her a few times a week if that. So every snake is different, and I don't think it has anything to do with the sex. I reckon I'm just lucky.
