hya my hermanns torttoise as just layed a egg what should i do with it and will it be layin any more

Hi
Here is a link on how to make a homemade incubator http://www.tortoise-protection-group.org.uk/site/154.asp
You need to get the eggs in a warm room or warm airing cupboard until you can get set up. Has she laid any more? I would take her to a tortoise specialist vet, to make sure that there are not any more eggs or that she is becoming egg bound.
Sorry for delay in replying, hope you have been able to get some help
