Mourning Doves have been incubating for more than 6 weeks - are they dead?

I have been watching 2 Mourning Doves take turns incubating 2 eggs on my balcony for well over 6 weeks now. I am assuming they are dead, and yet the pair keep sharing the nesting duties.
What should I do? I am hoping to re-gain access to my balcony soon, to plant and enjoy the warming weather, but am hesitant to disturb the birds & eggs. Should I get rid of these "dud" eggs?

Hi Ben. You can read more about Mourning Doves, on this page of my site; Mourning Doves. Are you sure, it has been 6 weeks? One could candle them to see if there is a live embryo inside.
Keep us posted.
