Here are some numbers from our flock- hatched 10-19, 2 of each breed.
The two that started laying first are still laying the smallest eggs- small and mediums.
The Easter Eggers consistently give large eggs as do the Australorps, one of the Barred Rocks and one of the Speckled Sussex. The Buffs have given us many eggs, but they are usually small to medium.
