how long will eggs last

[chrisarvor]

I am trying get some eggs delivered to me form the UK ,i live in Bulgaria
Do you think the hatch will be ok to incubate or will they have expired

From UK to Bulgaria is about 6 days for post to arrive plus the time before they were sent ??????
Any help

You may not get the best hatch rate, but as long as you are sent fresh eggs, they aren't jostled in transit, and everything goes well with incubation, you could get chicks.
Ideally, you'd want to set them within 2 weeks of being laid.
