I have six hens, two each from three breeds. After Christmas the gift poinsettia went into the backyard and chickens got to it. Nothing happened except one breed (Americaunas) stopped laying. Of course, that was mid-winter, so they may start up again in spring. But if they don't, I'm thinking about getting rid of them. Any advice? Is my connection between the poinsettias and no Americauna eggs even reasonable?
