Thats good! A small tear will allow it to move better, and no bleeding means that it is very close to being ready. The membrane is what I thought from what you have described. After having so many different kinds of problems with hatching, I will only assist now by wetting membranes. A while ago I had a little one rupture the yolk with its foot. I got home from work just in time as much longer and it would have drown. Every time it moved to get its head above the yolk - more would leak out. I quickly drained the egg- and the duckling forced its way out of a small hole very quickly after that- no unzipping- It just PUSHED!
Just try to keep it moist. I usually wet down the egg every two to four hours depending on how far along they are. But it sounds like things are very close now and hopefully you will soon have your little one out. There is usually some gooey stuff in the egg that comes out when they hatch- it may not be the yolk. Give it an hour or so and wet it again - especially around where the tear is to ensure it doesnt get stuck to the baby. Talking to it could help as well. They do talk to each other from the egg while hatching and that encourages them all to keep moving.
FunnyBunnies12...we all have to start somewhere...I have been raising waterfowl for 26 years and there is still alot I havent learnt or experienced yet. Being a part of a forum like this exposes people to all sorts of issues- good and bad they they may never encounter in their own flock.
