Hi, BYC Friends! Obviously, I am fairly new to raising chickens. Our girls are appx. 6 1/2 mos old now. We have RIR, BO. one White Leghorn, and Blue Marans. They are not all laying yet, but the 23 pullets are yielding an average of 11-12 eggs/day. On two days this week, we have found eggs with soft shells. They broke open on one end. Is this a young hen's first eggs? Will it harden as she ages? All of the other eggs are beautiful and the shells are solid. I appreciate any help that you can offer.
