Pete's guide is a thorough, general guide to incubating and hatching. It's not going to address every issue that may come up as there are many and each case is unique based on circumstance. In your case, you have an egg that was sat on by a goose for a couple days, then moved to an incubator with incorrect heat and humidity settings. It seems like you're expecting a black and white answer when one can't really be given. There are varying opinions on ways people choose to handle their hatches, so you're going to get varying opinions on what to do. I am by no means an expert and have just had my first hatches this year, but, I decided to listen to the advice that was being given and just go with it. That's about all you can do. Celtic has given you suggestions on what to do based on what you have told her and what she has been able to see. If it were me I would follow her instructions and hope for the best!
