Help for goose egg that isn't progressing-- Baby is OUT!

Today is Day 29 for 2 goose eggs I set under a broody bantam hen.  Two nights ago I candled them and saw one that looked clear, the other was nice & dark with a big air cell.  Last night I held the dark one up to my ear and could hear the gosling scraping against the shell.  But as of this evening it still hasn't pipped.

I wondered if extra humidity could help, so I misted it with water from a spray bottle 2-3 times today, putting it back under the little hen.

Should I intervene?  If so, when & how?  I normally do not like to step in, but I'm wondering if this gosling needs extra help because it's being hatched under the little hen.  I have had goslings successfully hatch under chickens with no extra help at all.  I did have to help one gosling that a tiny Dutch Bantam hatched last year, but that baby had at least made its own pip hole in the end.  After 24 hours I just had to enlarge the hole only a little bit and the gosling pushed herself out on her own.

I plan to go look tonight after dark, to see if I can tell where this gosling is trying to begin to crack out of its shell.  Should I help begin its pip hole?  With what tool would I do that?

Thank you for your help!

I've never known the hen to do a thing to help an egg under her hatch, besides the weeks of devoted incubation of course.  I myself usually won't do much to intervene either, because if a chick doesn't have What It Takes to get itself out of the shell -- under normal circumstances -- it usually isn't strong enough to thrive.

When I have chicken eggs hatching under a hen I usually don't intervene at all.  When they're hatching in an incubator I'll watch and if one has been trying for an extra long time I may give it a boost.  Sometimes in the incubator the fault isn't the chick's but conditions in the incubator. 

The same thing goes when there are duck or goose eggs hatching under a chicken.  I try to leave them alone to work themselves out on their own, but watch more closely because the conditions aren't as natural as they'd be under a mama duck or goose.

So, does anyone have advice as to how I could assist this gosling?  

When I candled tonight I could see a beak poking into the air pocket.  I could hear the gosling peeping too!  I don't know if misting it with water is doing anything to help, but I did it again anyway.  And my little boy & I prayed for the gosling to break through. 

If it hasn't pipped by morning I'm going to break a little hole in the egg on that end.  Goose egg shells are really hard, I don't know what I'll use to make the hole.  I need to find something that will make a small hole without cracking the entire shell.

 So this morning I see a tiny pip hole in the egg.  I in my infinite idiocy take a pair of scissors and make a littlelittle snip on either side to enlarge it, to help & encourage the baby.  I cut on one side and everything is fine, the membrane was a bit dry so I figure it may have been working there for a while.  Then I snip on the other side and it starts to bleed from the membrane.  AAAAAAA!!!!  I ran into the house and put a tiny pinch of flour on the edge of the pip hole to staunch the bleeding.  The baby is peeping away inside, but seemingly not in distress.  I sure am, though!  Lord Jesus, I pray that I didn't harm this baby, help it to hatch out fine! 

I have to leave for several hours now, maybe that's for the best, I'll be checking as soon as I get home.  This whole business is so nerve-wracking, you always second-guess yourself wondering should you help, should you sit on your hands...

Please pray for this gosling, thank you! 

I didn't get home until late this afternoon, checked on the gosling and it's still alive!  Still chirping, seems to have enlarged its hole a little.  There was some drying membrane covering it so I gently nudged it aside, trying to encourage the baby to start pushing.  I spritzed the open hole with a fine mist and put it back under mama hen.  It's been an hour & a half, going back out to check again.  Please, Lord, let this baby hatch and thrive!
