i am looking into expanding flock. I have a high demand for eggs and I have extra eggs each week but not nearly what I am asked for by friends and family. I am Looking for a great layer. I have GJ, EE, and ISA Browns. The ISAs are amazing but I like the variations of colors in my flock. Which of the two would you recommend? I want high productivity and large eggs. I plan on getting another 12-18 layers.
