I have 6 chickens, 3 brown,two white leghorns and an astrolorp. The astro is the only one laying at the moment. occasionally i get a brown egg, but the lleghorns, who are the youngest have gone off the lay as have the browwn hens. One of the leghorns has been eating her eggs so have separated her from the rest but now she is not laying at all. It is fairly mild to warm weather at the moment so cant understand why they are not laying. maybe they are just spoilt and lazy.
