found 4 dozen eggs that were hidden in a pile must have been there a month

I would like to be
able to tell which pullets are laying which egg.

I did it on the weekend. I started to stalk the henhouse at 5am when I open the coop and turn on the lights.View attachment 1319093. I only had 5 hens and 2 nest boxes.
I went out every half hour. If a nest was occupied I waited. If not I went back to the house and back to the coop in 30 minutes. At time my hens usually finished laying by 9am. Lucky me they finished before 9.View attachment 1319099.View attachment 1319100.View attachment 1319104.View attachment 1319107.View attachment 1319109.
But they don't always lay exactly the same every day, as you can see in this pic.View attachment 1319132. This was laid 19 days later. GC
