why is my chick taking so long to hatch?

  ive been incubating an egg and its 3 days overdue, it started hatching this morning and is taking forever? it doesnt seem to be making any progress in the last 8 hours, do you think this will be a runt? last time something similar happened the chick was verry weak and grew up to be a small hen, could this be the same thing? here's a video

Some chicks take longer to get out of their egg shell then others.

I would guess that something is wrong with your incubator. Check the temperature and humidity to be sure they are right. The egg needs to be turned regularly. Good luck.
No, i don't think so, one of mine took an age to come out!
