Handling or moving. Once the laying flock is in place, limit any unnecessary moving or handling. Switching roosters or changing the pens population will also disrupt the pens pecking order and cause some temporary social stress in your flock. If external or internal parasites are present, get proper diagnosis and treatment. Limit the movement of children, dogs, livestock and vehicles around your flock as well as loud noises to prevent frightening the hens.
Predators also can stress the birds and create a decrease in production.
