However, most of the preparations that are needed to successfully take a flock beyond the conventional 72/76 weeks of age, will pay handsome dividends in any case. Let’s consider what is required to take a flock to a longer age in lay.

Knowledge of the pullets rearing history is always helpful, as is being involved in the veterinary health plan to address any known laying challenges.
