A friend's mother has had a pair of tortoises for over 40 years, which live free-range in the summer. I haven't been able to find out which species, but aim to do so. They have been observed to mate over the years and occasionally lay a clutch of eggs in the flower border. This year they laid some eggs around 8 weeks ago and this has only just come to my attention. In your opinion, if these eggs still look OK, might they still be viable if incubated in the right conditions?
Many thanks

Hi,  eight weeks is too long for the eggs to have been left out in the open, they need to be put in an incubator straight away.  I have heard of eggs that have been layed directly in the earth in greenhouses hatching, but that is rare as they need a temperature of around 31 - 32C and the correct humidity to grow.
