Need HELP ASAP!!!!! Hatching Problems

Hello I am in desperate need of what to do with my chicks that are hatching. I do not have an incubator instead I have a broody hen that has set 7 eggs. I have only done this once before so I am still a beginner at this. I have a rooster so all my eggs are fertilized and about 23 or more days ago my chicken decided to start brooding. I did not notice this for about a week. I know i'm a horrible owner I was so busy and I didn't think chickens would brood so early in the year. But when I did finally realize what was going on I moved her to a new spot where she and her chicks would be safe and happy for the hatch. After that I guestamated when they would hatch because I did not know the date on which she started brooding. Long story short the first ones hatched on 2/7/16. After 4 of them had hatched the mom started getting up to show them how to eat and drink. However when she got up I noticed three blue eggs that had not hatched yet. I was worried that she would abandon them now that four of the chicks had hatched but then she went to lay on them again. On Monday she had moved to a different spot and left the (STILL) unhatched eggs in the old nesting spot. Worried that they would get cold and not hatch I tried putting them under the mom in the new spot. She did not seem to mind. However today when I went up to check on them again she had moved to the old spot again! and left the still unhatched eggs... Ugh. I candled the three eggs left to make sure they weren't duds and could not figure out how to tell if they were still growing or not. I was able to identify the air sacs and saw veins on all of them so I think thats a good sign? But my biggest problem is that today when I went up to check on them one of the eggs that hadn't hatched yet had a crack in it and I could see the chicks beak poking out. It was chirping and I thought it was stuck. I freaked out and did not know what to do so I tried helping it out of the shell. I got it out and tried putting it under the mom but am so worried that it will get suffocated or something. There was a little blood on it and after freaking out about whether or not I should have helped it I read that you can help it but you should give them time to do it themselves. I also read that if the yolk sac is not absorbed all the way before it comes out of the shell that is not good either. Keep in mind I read all that after I helped the chick out I checked its shell after I got it out and a little of the sac was not absorbed all the way... I am so so worried that I could have possibly killed it or that it will die. SO MY QUESTIONS ARE: what do I do about this chick that I tried to help out of the shell? Will it die? Is there anything I can do to help it? ALSO I still have two eggs that have not hatched yet!!! I think THEY WERE LAYED ON DIFFERENT DAYS which is why they didn't hatch the same day as the first four, so Do I try to stick them under the mom to see if they will hatch?? WHAT DO I DO??
ANY HELP WOULD BE MUCH APPRECIATED I AM DESPERATE.

Did the rest of them hatch

The last two have not hatched yet that I know of.

Alright well not all eggs hatch they might have been fertile but they could have died after so long in incubation but what day is ur incubation process on as about day 25 I would remove the eggs that did not hatch and do an autopsy on them to get and estimate of when they died or even if they formed hope this helps
