As far as I’m aware, 72 hours is the general guideline for hatched poultry like ducks, geese, and chickens. This is why they are able to be shipped without too much worry, they’re still working off the absorbed nutrients. I have had zero problems with goslings that were in the incubator for 48 hours, on the other hand, opening the incubator while some were pipped has cost me those. I’ll admit this year has been my first for hatching goslings (done ducks and chicks for a while now), and it has been a steep learning curve. They are much more sensitive to humidity than the other poultry. You can absolutely try to grab them quickly, maybe mist the incubator before you leave it, but I’ve had 3 goslings this year die from getting shrink wrapped unfortunately, and more didn’t make it due to too high humidity, so it’s a balance for sure. Good luck, but I will say that personally I’ve left them in for 48 hours without problems and the general rule of thumb is up to 72 hours (though I understand the nervousness)
