After being away for several hours, I always come home and check on my chickens. I just check the nesting places. As you can see there are three more boxes on the top where someone could go to lay an egg. Nope; I'll just wait,thank you. I know you can't see her, but there is a chicken in the slot behind the one waiting.
And then again, maybe we won't wait. These three decided they would just do groupie thing. Or two couldn't hold it any longer and jumped in is more like it.
