Answer Details
The extra oyster shell meal supplied to breeding hens aids in hardening eggshells. Oyster shells are an excellent source of calcium, which is an essential mineral needed for the formation of strong and healthy eggshells.
Breeding hens require a higher intake of calcium than non-breeding hens, as they are producing more eggs. Feeding them with oyster shell meal, which is made up of crushed shells, helps to supplement their diet with calcium and meet their nutritional needs.
When hens do not get enough calcium, their body will start to use calcium from their bones to form eggshells. This can lead to weaker bones and increased risk of bone fractures, as well as soft or thin eggshells that are prone to breakage.
Therefore, providing extra oyster shell meal to breeding hens can help to prevent the risk of calcium deficiency and ensure that they lay strong and healthy eggs with hard eggshells. The correct answer to the question is: The extra oyster shell meal supplied to breeding hens aids in hardening eggshells.
