Does anyone know why my chickens for at least the past month have been going into their nesting boxes like normal but then coming out without laying an egg. My Easter Eggers are laying perfectly normal but my barred rocks and Rhode Island reds are almost not laying at all. I also have 6 new chickens and one off the Easter Eggers just start laying but she keeps laying in the run. Last time, they started laying in the coop on their own. Is there anything I can do to encourage her to lay in the coop?
