If its rough and could have a sort of sparkle about it, then its possible its an over calcified egg.
This can happen if the female cant find a suitable nesting site with correct temps:0)

I agree its an over calcified egg. I lost 3 hatchlings just last week. They pipped but promptly died😩 I noticed the eggshell was very hard. I spoke to Dan & of the possible reasons we went through the likeliest cause seems to be Mom being gravid & not liking the nest sites offered. These eggs weren't actually rough, but were too hard for the hatchlings to break out of easily.

I wouldn't incubate a rough egg.

Thx
One more question, for the past few years, my tortoise only lay 1 or 2 eggs per clutch. And almost everytime, the egg burst during laying
Any idea?

If the egg bursts then its possibly/probably a lack of calcium in the female.
Make sure the female gets lots of calcium:0)

this is quite interesting because it can be the tortoise's make up ie it cant 'layer' the egg and the rubbery bit that binds it all together is often missing which may not be to do with the calcium levels at all but genetics. I am not an expert I read it in the BCG newsletter recently , probably bit too much detail, but if the process stages don't go as they should then the egg can burst. CB

Thx a lot
I just bring her to vet for x ray check
Vet said the egg shell not clearly visible through x ray
Thus, lack of calcium should be the reason for burst egg

An infertile egg that is way past its hatch date will also explode, it's as the insides start to rot, the gases expand the egg until the egg explodes, also lack of calcium causes a thin egg shell. One of mine keeps breaking eggs on actual laying because egg shells are too thin.
A rough egg is a calcified egg, the Tortoise has retained the egg for too long, usually because there's no attractive nesting site.
