The video presents beak clipping as a welfare improvement — without mentioning that beaks are nerve-dense and sensitive.
A welfare improvement that is forced because of the conditions. It, for me, did not present as viable, but as one terrible symptom of that state of agriculture. Like sterilising or murdering animals because humans, in twisted irony, don't want overpopulation, despite humans being the cause of animal breeding rates increasing over the centuries via breeding and manipulating the evolution of other creatures to be more malleable or palatable, and killing/culling them while claiming their land, citing superiority over all beings.
Kurzgesagt also omits common practices like forced impregnation, newborn-mother separation, and mass killings via gas chambers
Newborn-mother separation is mentioned at 6:00 and gas chambers are mentioned at 3:37, in the mentioned video.
