This clutch was from a Butter/Bee X Yellow Belly. Each male had three visually confirmed locks with the female. A few were within days of each other.
While females can retain sperm for up to a year, I suspect that breeding males back to back on a female will increase the odds for a split clutch. My five split clutches last season ALL had males "tag-teaming" the female.
I can't tell what it is, but in the first pic the snake in the top middle and (s)he is in the top left in the second pic...it has some CRAZY head markings...like absolutely ludicrous markings on its head. very nice clutch man!
