Blue tit eggs can you manually incubate

Ove had a blue tit laying an egg a day in a plant pot but on day 5 we had a freak hail storm and giant hailstones which filled her next with a block of ice and she stopped laying and hasn't returned. It's been 5 days and she's definately n9t returned. 

I dont like the thought of the eggs just failing so how can I go about incubating then and seeing if they will hatch?

Can they go in a normal egg incubator?
