Hen dietary considerations for improving egg quality

The amount of saleable egg produced per hen becomes even more important as cycle lengths increase along with a move toward cage free.
Egg quality declines naturally at the end of a laying cycle as egg size increases. Profitability of keeping hens longer requires nutritional support for egg quality. Diet formulation can influence the size and number of eggs laid. Calcium availability is key to shell strength but trace elements pay a key role in structural development.
