The Association for Protection of Animals: Animal Equality secretly has filmed atrocities to inform the public about the chicken industry meat making. This factory is American and there are similar to this one like in UK.
Chickens are born in hatcheries. Also these animals get trapped in the cruel meat industry, so these small animals have their first life day in incubator and are treated like hostile beings or machines.
They are separated from the mothers and this is awful since the chick spends the life mostly by his mom and her protection. No compassion here, only disrespect.
See the video yourself and see the terror in the chickens:
