My hens are around 2 - 2.5 years old. Still producing well. But our extra large eggs aren't often any more. In fact half of them are extra small. I know production drops in hens. But size of their eggs? Haven't seen this before. Changed them from Granulated feed first of the summer, And added 5 more hens in July. Believe thats the only changes we made. Any one have any ideas why size would drop.
