I get all my gravid females from the pit just after new year and rehouse them. I take all the ones that appear gravid and that way if they are just fat then you can put them back when you realise it. I am usually 100% but how would I know If I missed any because I doubt Id see any offspring that were born in the outdoor enclosure.
I had 12 born yesterday and when Id got home they had climbed mum onto the cage of the hanging bulb , climbed the flex and were sitting on the timber crossbeam that the light hangs from. A good metre.
