I have several hens that lay for me XXL eggs, 2 are RIR, 1 BPR, and 1 EE. They began laying this XXL eggs for me when I switched them from 16% to a 20% layer feed. Not only are the eggs all coming out bigger, they are also laying alot more efficiently. This was my first XXL, it had 3 yokes, most of the others large eggs as this has all been large single yokes.
