Hidden nest! How good are the eggs now???

Hi everyone! We noticed a big decrease in one of our hens and how much she was laying. I happened to be running around the yard today and looked deep inside the bush and low and behold there was a nest there. it had 10 eggs in it!! Question for you all… Are these eggs still good? My guess is she's been doing this over the last week or so, I just don't know. Help! It breaks my heart to think that I might have to throw them away!
