I have a lovely barred rock hen who just turned one year old. She's been acting somewhat strange lately in the sense that she will sit in the nesting box for about an hour AFTER she has laid an egg. Meaning she will lay her egg, go back outside, all the others will lay their eggs, then at some point during the day she will go back to the nesting box and sit for a while. Afterwards she will just hop out and go back outside. What's the deal? None of my other girls even go into the cool at all during the day except to lay their eggs. This hen is also the first to roost at night, even if all the hens are still wandering about outside. Does anyone know why she is "pretend" laying eggs?
