Average amount of eggs

I looked through the search but couldnt find any info on what the avg amount of eggs that are fertile during birth? I know size and health has a huge factor but just kinda curious what people usually get. I got a good size female I want to breed and been thinking of calling a friend at a pet store and seeing if i could do a breeding loan and breed her with a bumble bee.

from what I have seen the most successful everyday average clutch size is 6-7. Thats if you get any at all:weirdface
