Egg production and quality are greatly influenced by the physiological status of the laying hen. In this chapter the effects of bird age, moulting, temperature, lighting and housing system are discussed in relation to how consistency in lay and egg quality can be optimised and maintained. The environmental conditions experienced by a freshly laid egg during transport and storage are also critical if the freshness of the egg is to be maintained throughout the logistical chain. Optimal conditions for egg handling and storage of eggs are therefore discussed in the final section of this chapter along with new technologies which may be implemented to ensure and extend the shelf-life of eggs in the future.
