I have pair of calls...hen is about 3 years and the male is about 2 years older. The hen has an angel-wing, but she has layed soft shelled eggs for about 2 years straight. They are on Egglayer pellets, i have offered fine oyster shells, and even tried forcing a Tums at a more serious time when I though she was egg bound. This year, out of I dont even know how many eggs, 2 were shelled, but EXTREMELY thin. What am I doing wrong or is there something wrong with her?
