If you watch Super Size Me 2, they go into a lot more detail on why the selective breeding is so disturbing.
Amoung other things, the birds are bred for meat muscle development, their cardiovascular systems have not been equally enhanced and as a result, chicken farmers know that the birds are big enough for slaughter because some of them will just start dropping dead of heart failure.
Piggybacking on this comment, but i never realized until I started keeping chickens that meat birds get so disproportionately huge that you can’t allow them to roost / have to have a ramp out of their coop. If they jump, they’ll blow out their legs when they land and just…die. They’re literally bred to be incompatible with life, as no one really needs them to live long anyway.
