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.

There was one normal boy who was nudged out of the picture by his sibs.
