I know this is probably hard for you to hear, but really you should leave the pipped egg alone from now on. If you help that chick anymore you could end up with a very weak and/or deformed chick. That will be much much more heartbreaking to deal with--- I promise. You think you're sad now? A barely living chirping chick will be even more devistating. I have personal experience. Don't do it.
I am a huge animal lover myself (I think everyone on this site is!) and honestly, my first few hatches I balled my eyes out constantly. It was so stressful that I would swear I couldn't handle it anymore-- then after a week or so try again. It's a learning experience, but very difficult to accept failure when you're dealing with a sentient being.
I have met ALOT of friends who have also admitted to feeling guilty when their hatch doesn't go as well as they wanted--- but you have to learn from it. It's part of life & it will get easier, it doesn't make you a bad person as you obviously care.
You have a ECO, which is great, but there is definitely more of a science behind it because you have to monitor everything yourself. Get several thermometers (wet & dry) for next time---you'll be surprised how different the temperature gradients are.
If after a few more days nothing happens with your current hatch, I would recommend you call a friend or a supportive person in your life to come over and help you dispose of the eggs. Clean out your bator, have a good cry, and if you're feeling up to it, do all little "egtopsy" and see what went wrong. I understand if you don't want to do it (I had my BF dispose of the eggs the first time & do the eggtopsy himself--he's got a science background) but if you want to continue hatching it's very helpful to find out what you can do differently next time. You might even discover that the eggs weren't even hatchable & you did nothing wrong.
Good luck & I hope you can enjoy your weekend
