During December, the 315 hens of Ecotone laid a total of 353.04 dozen, or 4,236.48 eggs. Along with the cold, the increase in the number of eggs laid has increased the amount of grain the hens ate, up from last month to 78.55 pounds of grain per day. That works out to a grand total of 2,435 pounds of grain, or 6.90 lbs. per dozen.
The daily average for the month of December, then, was 11.39 dozen per day, or 136.66 eggs per day, which is a monthly rate of lay approaching 44% -- not bad for heritage breed hens!
Above and below are photographs of several eggs from a single day of lay in the flock. Note that the extra-large one had two yolks, while the smallest had none at all. It does indeed take all types!
