I have a mixed flock of birds, mixed breeds and 1.5 to 3 years old. They layed until mid summer and then all stopped! I haven't had a single egg for 2 months! Here are the things I've tried... changing feed increasing amount of feed cleaning out coop giving more oyster shells deworming electrolytes in water apple cider vinegar in water What am I forgetting!? Some have molted in the last month or two but hardly any have laid for nearly 4 months! I'm about ready to start butchering because we can't afford to feed a flock of 15 if we aren't getting any eggs. My ducks are more temperamental layers but they too have stopped laying.
