Are they still worthy canary eggs?

My pet canaries laid 3 eggs. First one 15-16 days ago, still none has hatch. The Hen will not leave the eggs for more than 2 mins a time. Are they dutiful? Will they hatch? I have not touched them, as I do not want to switch them wrong. Should I just be tolerant?
Answers: No, the eggs are not good in a minute and need to be removed from the hen. Can be replaced beside a plastic egg like they supply for Easter, so she doesn't keep lay.

Did this feamle mate and breed with a manly, or is she just lay infertile egg's?
