my first clutch of eggs looke like those 30 days befoer they hatched ( most though they were dead) Igot 5 beatiful snakes out of them. and there was 5 eggs. I watch them closely. asfor them plumping back up I doubt that will happen. I aslo say on day 53 nip cut them cause what happen with mine was the shell part stiffen up and would of been harder to get out of. I am cutting the onesI got this morningon day 53 ( if they start to look rough befoer the 40 day mark)
