Can a chick bust its yolksac while still in the egg? Will it still be able to hatch?

The chick pipped below its aircell. The pip hole was crusty. I pulled enough shell off to unstuck the membrane of its beak. It was starting to shrink wrap. I made the hole big enough to get a qtip in there to rewet the membrane. I put the egg back and raised the humidity even higher. The membrane was crusted up and stuck to its wing. I used a qtip to loosen the membrane where it was stuck. The chick was blowing bubbles.I tipped the egg to make sure I didn't get to much water in the egg. When you tip it yellow sticky fluid pours out. Did it bust its yolksac? Will it be able to hatch on its own or is it going to end up stuck in its shell?

If the chick is normally positioned, the mostly absorbed yolk sac will be below its feet at the time it pips. Unless interfered with, the chick will normally pip, rotate and zip and those movements help the yolk absorb.

If the chick is malpositioned and kicks and tears the yolk, it will usually lose blood too, as the yolk is still covered with blood vessels at this time. Besides the risk of infection, aspiration of yolk, blood and fluid often cause the death of the chick.

Best thing to do is to leave it positioned with the beak at the highest point and leave it be. Chances for survival don't sound so good, though.

It pipped yesterday morning and hadn't progressed by last night. So I pulled part of the shell rewet it and put it back. Checked on it tonight still no progress so I unstuck its wing. Its still peeping and trying to turn itself in the egg. Could it be from not losing enough moisture there is no blood in the fluid.
