It's hard for me to see clearly, but it doesn't look like an egg that's going to hatch. I see too much light and no clearly defined air sac. The blob you see is most likely the yolk. Or a chick that started to form and died. Again - compare it to the pictures in the link I sent you - if it doesn't look like that, it's most likely a dud. If they all look like the picture you posted, I am quite confident in saying they will not hatch. You should not be able to see anything but the air sac at this point. The rest of the egg should be dark. See if you can find some chicks for your hen, slip them under her and take the eggs away. When you take the eggs, - if you're comfortable doing it - open them up and see what's in there.
