No they are not “fat like that” because they are penned up.. they are bred to be that rediculously large. Selective breeding has produced turkeys so rediculously large breasted they can’t even reproduce naturally...
While you are free to criticize the industrial farming of chickens, they aren’t fat like that because they are penned. They are fat like that because they are genetic freaks bred to be that way.
Sorry turkeys. Not chickens.
Who’s complaining? The fatter the better!
Raising my own Tom Turkey is on my Bucket List. :)
