Due to starvation before and during transport, weight losses up to 15% of body weight may occur.

* The basis for switching between diet types is the hens‘ body weight development. The correct time for changing the

diet is determined not by age but by body weight. Chicks and pullets should therefore be weighed at regular intervals.
