Hey T. Here are some percentages from our breedings this year:
Of those females that were bred and locked, how many laid - 72%
Of those males that we tried to breed, how many refused - 0
Of those clutches that were laid, how many turned completely bad - 0
Of the eggs laid, how many were slugs - 8% (one female laid 8 eggs and 5 were slugs, all of the other slugs were singles within a good clutch)
Of all the eggs laid, how many individual eggs went bad during incubation - 3%
Hope this helps.
