Chick having trouble hatching

I have only one egg that has hatched so far the chick was fine it was a quick hatch. Now I have another one trying to hatch since this morning I know it can take them a while but I think I see the beak where it's not supposed to be according to how the chicken is supposed to be hatching. It has started to work harder now but still struggling. I am debating if I should help it or not. I have had troubles with humidity and I'm worried that it could get chilled over night. More pieces were breaking off but I'm still a bit worried. Any advice is greatly appreciated.
