What causes soft shelled eggs?
Soft-shelled eggs are common in young pullets just starting their laying career. In older hens, it is usually caused by a calcium deficiency. To remedy this, give the hens free access to shell grit or finely crushed egg shells. This helps increase the calcium levels and the problem usually stops. It is a good idea to allow fowls to have shell grit all the time, as they need certain grits to help break down and utilise their food.
