Thanks James,
I am 100% clear on the mid-body scale counts for the 2 species - but I think I will wait to retrieve the next sheds !! It saves wrestling with the little darlings (some of whom are very obviously gravid), and in the interim I'll just segregate any offspring that happen to pop out - and whatever they are today they will still be the same next time they shed.
Have an enjoyable evening.
Cheers,
Brian.
