Why not? RSL are supposed to lay a large to extra large egg. They are the industry standard brown egg layer for eggs you see in the store. In large laying houses they control the final egg size by limiting certain proteins in the feed when the bird is still laying pullet eggs. We can't do that at home, so RSL often lay very large eggs in backyard chicken houses.Wow I never would of guessed that one due to her egg size. Thanks!
