Farm size has increased significantly in recent years. However, French farms are still of modest sizes compared to many other countries. Scientific publications do not show a direct link between animal welfare and the size of a farm. Larger farms potentially present more risks for animal welfare, but also certain advantages in terms of better management (greater investment, etc.). Access to the outdoors is the most problematic issue. Animal welfare depends mainly on farm management, which is specific to each farm regardless of its size.
