EFSA scientific opinion on the protection of domestic birds and rabbits during transport. The main welfare consequences during loading and unloading are handling stress, injury, restriction of movement and sensory hyperstimulation; those while travelling and on arrival are injury, restriction of movement, sensory hyperstimulation, movement stress, heat, cold, prolonged hunger and prolonged thirst. These welfare consequences and the indicators measured on the animals are described. The hazards that cause them, and recommendations on how to avoid such hazards and to correct or mitigate their effects on welfare  are presented.

Scientific review identifying an increased risk to free-range hens of microbial and parasitic infections, heat stress and predation. They do, however, have better bone quality and show less evidence of pecking behaviors. The review sets out existing preventive strategies and identifies missed opportunities to use genetics and prenatal and nutritional factors to prevent these welfare issues in free-range systems.
