to help with their digestion.
All chickens go through molts. Some hens will not lay very well, or the eggs they produce may not be the best. Continue to give them constant access to oyster shell, plenty of grit, with a GREAT diet (layer feed, plenty of extra protein, etc).
Yes
oyster shells
You can only make shells thicker BEFORE they are laid. That is why hens that are laying are fed oyster shell. It supplies calcium for good egg shells. If a shell is to thin, it breaks to easily, if it is too thick the chick cannt "pip" which is a term for the chick pecking a hole in the shell as it hatches. If the shell is too thick, then the chick can never be born, and winds up entombed in its own shell, and very dead.
An oyster - bi (stand for two) and valves (stands for shells) - two shelled animals.
The oyster's shell provides protection from predators. Oysters do not need to shed their shell because the eat and expel waste products buy opening their shells and pumping water in and out with hairlike structures call cilia.

Oysters and mussels do not shed their shells. They are bivalve molluscs and their shells grow larger with age.
Give them grit and crushed oyster shells or, from personal experience, I have found that cleaned, crushed eggshells will also work a treat. The grit and oyster shells must be specialist chicken ones.
NO. Hens will do well on scratch grains and corn but the addition of the extra proteins and calcium in layer feed make better quality eggs and shell. Without the layer mash you will need to add a source of calcium such as dry ground egg shells or oyster shells.
