It’s important to collect the eggs regularly so they aren’t damaged by the hens. If an egg is cracked it should be removed immediately to prevent the hen from eating the contents. If a hen does begin to get a taste for it, it’s a difficult habit to break and the hen may even try to intentionally break the egg for its’ contents.
Soft shelled eggs can be produced by pullets as the egg may have passed through the oviduct too quickly. A couple of weeks after the hen first starts to lay, the eggs should be normal. If you experience a regular occurrence of soft-shelled eggs, this often indicates that the hen is lacking calcium.
