Infectious diseases pose a huge problem in poultry farming. Poultry farmers are often forced to rely on antibiotics to tackle this issue. However, this can sometimes result in germs developing resistance to these drugs. These resistant pathogens then find their way into our food via animal products. The frequent use of antibiotics can therefore pose potential health risks to both animals and humans.
Or, keep only as many birds as can freely roam outside in the sun, where they self-disinfect with UV light and soil. Squeezing too many members of a species in too small a place is cruel and makes the animals sick, doesn’t matter if it’s chickens or humans.
