i use individual continers for each batch,bugger having an incubator full of vermiculite,alan?icecream containers work fine for me and I think the reason is they re not completly irtight,but pretty much so?Those takeaway continers would be a bit the other way I think?As for the moisture level,turtles need a bit more moisture than beardies but less than boxies.torts are different again,and although drier I have a small open container of water as well.I am not as paranoid as I once was and just go by what I see and feel.One thing I think has helped alot is to use boiled water that has cooled down and keep your vermiculite as clean as you can.I used to wet it alot nd zap in the microwave but don`t bother with that these days.The worst hatchs I ever had were red ears in floating aquarium with heated water,embryos physically drowned and eggs even burst with osmotic pressure.I can tell from the dampness of the paper towel covering the eggs if the container is wetter or dryer than the last check.Weekly is not too much of a chore and depending what you are trying to hatch always worth doing.
