What I mean to "humanize" animals are these traits that we humans put upon our chickens, particuarly dogs and cats. It is more for US to feel good but not necessarily feels good to the chicken.
Yes they do have the responsive stimuli in how they were cared for, feeling pain, feeling protective of their flock and chicks, that is normal all across any species of animals.
However the line is this, not to bash anyone for this but to their own......you dress a chicken because they are "cute" in tutus and dresses, that is way over the top IMO. Treating like a spoiled baby that one would sideline their lifestyle that their world evolved with their pets, buying and thinking it is best for their pets to be that way. Some pets are beyond to the point of destruction that they know how to manuliplate us, to feed them more of "junk food" because they "cry". Because they "cry" is the normal response...remember the Pavlov treatments in dogs? Same thing. Are we doing them a favor, probably not, simply because we FEEL good in doing that kind of treatment. I am sure we have our favorite chickens and we would treat them a little more special than the others while the others dont give a hoot about it as long they get the treat in your hand or a fond petting that certainly makes them purr.
Some folks go way beyond that stage that it would make their chickens unhappy. It is our own selfish needs to "humanize" chickens so we can feel good about ourselves and for the chickens (bad or good).
Chickens have basic needs like we humans do too but we humans need a little more. I hope that clarify what I mean about humanize chickens.
I am against battery hens.......I certainly do not want to be like them, crammed in a small cage and only to produce eggs in my lifetime. You can bet the farmer had to block that mentality so he can support himself and his family along with the employees. He does not have the time or money to treat every sick chicken so what he do, eliminate them. "Cage free" birds are a little better but still problems does exist the same for battery hens as in space and confinement in a barn, not in a field.
