Every day we are getting a large soft shelled egg. The shell feels ok but it is very fragile. It breaks really easily buy just picking it up. Or another why bumping it. The only other thing I have noticed is the color of the egg is paler than normal. They are usually darker. Our girls vary in age from 1 year to approx 4 years old. I am assuming it is one of the older girls but not sure. They are feed 16% layer and have oyster shells available free choice.
