These darn geese nested in the exact same spot again! I contacted the people who own the silage pile to inform them. They said that they're going to be coming for silage the next day, so I had to remove the nest or let the eggs be destroyed..
I removed the 4 eggs and stuck those in the incubator as well. Of the other 7 that I rescued, only 3 were actually fertile. They are busy hatching right now.
Of these 4 eggs, all of them are fertile and developing. They're on day 5 right now, due to hatch June 6th.
Hopefully all goes well.. We still have to scare away the parent geese almost every day! They keep coming back to nest there. I'm guessing we'll have the same problem next year.
