Help! Geese eggs due Saturday (4/27/2013)

[foxfarms]

I ordered 7 geese eggs off the computer, 5 made it safe and sound and I started incubating them that night after I let them rest from being in the mail. I have misted them with a spray bottle 1 a day and then about a week ago I started doing it twice a day. The temp has stayed at 99 like it is suppose to and I have turned them all 3 times daily. I am getting a slightly different smell from them as of yesterday but I can't tell which one and I haven't candled them in about 3 weeks but I don't want to hurt my chance of hatching them out. What do I do? Do I just wait until Saturday and see? Thank you!
