hi

i have a female spider which i have bred to a pastel and a lesser, both locked up on many occasions and i am sure she is gravid now, when i palpate her i feel 4 large lumps in the back half of her body towards her tail, they are about the size of small plums, my question is how large are the eggs before she goes in to her pre lay shed? or im thinking i may have missed the pre lay shed so what do i need to look for?

many thanks
