It does take them extra time. But after that extra time... no progress is no progress. I give chickens 2 days and ducks get 3. Haven't tried geese but it has to be the same concept. If it's still stuck, here's what I do.
Supplies-
Paper towels
Shallow tray lined with a paper towel (I use take out food plastic trays, 7x5x2 inches there about)
Cup of warm water (99 degrees)
I start chipping shell, small bits, very carefully, trying not to snag membrane. My goal is to expose the inner membrane without hurting it.
If I hit a lot of blood, I stop and wait a couple more hours. A lot of blood means you're early, it's still absorbing. Another reason to wait a day or two after pip to be sure, takes time for things to absorb. If the chick pipped early, but then made no progress, perhaps they know not to continue as well. I've never seen a lot of blood around a zip in the amount of when you help early, so they must know when to continue and when to take a break.
If you manage to get the inner membrane exposed, dip your finger in the water, let a drip fall off of it, then touch the membrane. The blood veins will light up like a christmas tree. If they're very dull and almost brown, you can continue, the blood has receded. If they're bright red, there is still a lot of blood in there, and you need to wait. It will recede along the zip route, away from the pip hole. You can get most of the way around and hit a gusher on the back side. So be very careful and very patient. I don't know how much of that blood they can stand to lose.
It can take 24+ hours for a chick to do what you can do in 5 minutes. Never just break a chick free unless you don't encounter blood. It's best to work in stages like they do unless you know it's just been too long and you're not finding any active blood vessels.
If you free the chick, dampen the paper towel in the tray with the warm water (prevents the yolk area from sticking to the paper towel) and place the chick on it, feet under itself in the proper position, and put it back in the incubator. It will need to sit in there for a good 24 hours to regain it's strength and dry out.
Use the amount of blood as your guide, stop when you see it. I try to get to where I can see the veins without damaging them. But don't start the process until you know it's good and stuck which is 2 days or more from the first pip. Unless it pipped early, then add another day.
Also, if there are more eggs in there, don't risk the majority for the one, wait it out until others have had their 2 days+ to get out.
Good luck!
