I have a RIR that's been sitting on 8 eggs and they are due to hatch July 1st. Over the weekend we went to the lake and didn't come home till the next afternoon. When we got home about 3pm I went to collect eggs and my hen was laying in the wrong nest on the eggs that had just been laid that day. I'm wondering why she is getting confused as to what eggs she's been laying on for the last two weeks? It's not always possible for me to collect eggs early because I'm off to work before all the girls have laid their eggs.
