I've been very suspect of another outdoor(outside of their coop/run) nest. I finally saw my hen go into the nest. I let them out in the morning and lock up when they go to bed. I live on National Forest Land, so, there's lotsa hiding places. 6 of my 9 hens are pretty good about keeping in the coop. My max egg count for a day was 8...... What about the eggs? Good still? Toss 'em?
