Thank you for the suggestions. I will try some of those if I do not see him breeding in the next couple of days. I did pair him with my only experienced female (I just bred one pair last year), but as I told my husband, if a snake could run screaming, he did from her. I suppose it wouldn't be the worst thing to have some more killerbee combos. All 5 of his offspring from last season were female. Probably just luck, but you never know.
