Is my egg going to hatch?

[QuailMcQuail]

I have an egg in my incubator that hasn't hatched yet, the rest of my eggs hatched 2 days ago. So I'm wondering if this one will hatch. I have tried candling it, but the torch isn't bright enough or shell is to thick it just doesn't seem to allow the light in. I am yet to see if it sinks or floats. However I think I have heard tapping coming from the inside of the egg, I'm not certain, but I think I have.

I'm wondering whether to leave it and see what happens, or poke a hole in it in case the chick is struggling and needs oxygen.

What do you think I should do?

Any help is greatly appreciated thanks.

What day is it on?

I mean did the others hatch on time? 21 days?
Were they shipped eggs?

I think the all hatched on time, I wasn't counting as they were originally with their mother, but then their mother decided to abandon them which was when I put them in the incubator.

Ok, it's possible she started sitting on them on one day, and this egg could have been added later.
If there is still no movement from the egg, and no external pip, I would float test it.
As long as there is no external pip, then I personally would float test it.
Please read the hatching 101 before you start poking a hole in the egg.
There is a particular way to go about it, and if done incorrectly could cause more harm.
