My oldest hen has been throwing soft shells for the past couple weeks. I suspect it's because of a deficiency of calcium in her diet. My flock is currently on chick feed because we have a few youngsters in the crowd. The three older pullets are almost laying age so I'd feel comfortable switching over to layer feed if it was just them but we also have a little one who is only 10 weeks old. I know switching them to calcium feed too young can be bad for their health, but how young is too young?
