missing chicken

an update on my missing chicken— I found a nest with 3 eggs in it. Judging I saw her every single day on multiple occasions throughout the day and suddenly disappeared for 4 days and going (I also tested the eggs buoyancy to see if they were fresh, which they were), is it possible she has another nest somewhere? I checked every single place on my garden and didn’t find any other nests, feathers or trace of her. Why would she abandon the one i found so quickly assuming the eggs were laid recently?

I seriously im investigating this like a police case asking neighbors and guards where and when last saw her and finding clues. I’m just really hoping she comes back soon and wasn’t taken by someone. (We dont have any predators that can kill a chicken)

Any ideas? Or should I face the fact I may never see her again?
