They make awesome pets too as long as they're social. Mine love to cuddle like little feathery dogs. XD

I just now watched the video. It is outdated and not a standard used in modern slaughter houses. Debeaking does still go on, which I find inhumane since chickens should not be kept in such crowded conditions to be fighting to begin with. The birds are healthier, happier, and lay better tasting eggs if they're left to free roam and eat a natural diet.
