If by “proper” he meant normal or natural, then he was correct.So, here's a question for people to think about.
Was Mr Young right and battery hens are not proper chickens?
I don’t know that they need to learn to be chickens. I believe they only need an environment more conducive to their natural behaviors. If they are older and fully conditioned to their battery cage, they may not have enough time for those instincts to emerge. Sadly, those would die stressing in their unfamiliar environment and never achieving “chickenhood.”....
Could they ever learn how to be proper chickens, particulalry given they have such short life spans in which to learn given the opportunity?
If introduced to a better environment early enough, natural instincts may emerge. They would become “proper” chickens.
