Khaki Campbell nest outside

[mswendeu]

Good evening I live in southern chautauqua county in NY state. My kc laid quite a few eggs next to our barn. I have been away for a couple of months and found them on a return trip home. I am new to this so wondering what to do? How long do I wait? Will she hatch them on her own? She is sitting on them and doesn't come off from there very often. I'm not sure how many eggs are there because I don't want to disturb the nest. Any and all help will be appreciated. Thanks in Advance.
Note: I found her nest Sept 26th so it's been almost two weeks since I found the eggs.
