I got 2 ready to lay-RSL chickens this past September from Freys Hatchery. I figured they would lay pretty consistently this winter because of their age. One of the hens lays XSmall eggs. She does lay regularly , but the eggs are so tiny I feel like I can't really sell them. She is healthy and acts normal. Does this sometimes happen? I thought RSL were bread for large brown eggs with high production. We've now had her for almost 6 months, and eggs remain small. Is there anything I can do to increase the egg size a chicken lays?
