The report documents the scalding, starvation and mutilation of birds as well as the potential for the spread of disease from chickens to humans, a PETA release said here.
The disturbing findings were sent to West Bengal government last year, and it was warned about how unsanitary conditions on factory farms could lead to an outbreak of the deadly H5N1 virus.
PETA's report reveals how unhygienic conditions are responsible for the repeated outbreak of bird flu in India.
In 2005, approximately 2 billion chickens were slaughtered in India. Chickens are crammed by the tens of thousands into dark, filthy sheds, where the ammonia from the accumulated waste actually burns their eyes.
Peta said chickens used for meat are pushed to reach their slaughter weights in just 40-42 days. Typically, the bird's legs, hearts and lungs fail to keep pace with their rapidly growing bodies, which led to serious problems. The legs are so severely crippled that the birds are unable to reach food and water, PETA said.
