Thanksgiving is a tradition for celebrating life. Sadly, during the holiday season, more than 45 millions turkeys will be slaughtered for their meat, many of them treated with extreme cruelty.

In 2013, an undercover investigator from activist group Compassion Over Killing recorded a documentary, illustrating the brutality and harsh living conditions that turkeys are forced to undergo inside Hargin Inc., a breeding facility farm in Minnesota, including squalid, cramped surroundings that cause many hens to suffer from extreme ailments.

In fact, the vast majority of these birds will spend their entire lives confined to sheds and subject to inhumane exploitation. The process of artificially inseminating the hens is a violent and frightening procedure in which the birds are grabbed by the legs, held upside down and stabbed in the genitals with a plastic tube to inseminate them.
