a few questions on incubating

[reptile boi]

Hey,
When you gise incubate eggs in a hovabator do you put them in rubbermaids WITH the lids on? If so, then how do you get the right temps? Also, i have been seeing that in some pics from people like jeff favelle who puts his eggs on those plastic egg crates (Theres another word for it but i forgot what it was) and leaves that over vermiculite and i was wondering why do you do this? Does it give you a better hatch rate?



Thanks,
Ben
