How small are those young? These species are already tiny to start out with, right?
Why do you say to put her into a smaller container?
Isnt it more natural (as far as natural can go within a terrarium) for her to drop them where she lives? She knows the places where to hide or seek less humidity or heat? Handling her while she's dropping doesnt seem healthy to me either.
THis is why I ask, out of curiosity, not to know better...
