Found Goose Egg, Help Please

[goslingmomma]

I found this goose egg on a trail about 6 to 7 days ago and have been keeping it incubated at a steady 99-100 degrees. This is my first time doing this but when candling tonight, I saw a small round red speck near the yolk but no veins. It looks like it may have something in there, can anyone tell me if it is fertile

and how long it will be til hatching?

Im not sure if it is fertile, try leaving it a couple more days and then candle it again, if you dont see any veins than it probably isnt fertile. Are you sure it didnt have a mama that would go back to it? Anyway good luck with the egg.
