some of my eggs take 90 to around 120 days i like the temps on the lower side,69 to 74. In my experience the longer they take to hatch out the stronger they seem to be and bigger as well.for a while i was having a problem with the babies hatching out then not making it,some within a week,some a few months.im still trying to correct this problem..as far as incubating mine i like the clay balls on the bottom and then the screen mesh sitting raised a few inches above that with about 90 percent humidity. this is just my method take it for what its worth...i am also open to any suggestion thanks brad
