Almost all domestic animals are dependant, thats how mutualistic symbiotic partnerships work. Humans are only recently arguably capable of abandoning that dependance, none of our symbiotic partners can match that. Im really creeped out by what youre implying here, we shouldnt kill off our evolutionary partners just because we dont need them any longer.

And… “Bred to rely on said diet” is a crazy thing to say, no? All animals rely on their diet. Some breeds of chicken have a higher calcium intake requirement, but so do some breeds of human. Not an excuse nor reason to drive either extinct.

Thats only if you arent feeding them a regular source of calcium.

Which would happen to literally any animal not properly fed.
