Daily Routines Changes or Different Staff in Laying Hens

Many management factors may cause an apparent egg drop. By example: changes in daily routines, timing, excitement, different staff (at weekends for example) can all have an effect as can sudden noise and disturbance (planes, drills, lorries, dogs, etc.). Recording systems and timing of counts must be similar day to day (so must egg collection times).
