There are so many opinions on the subject. Even though "no one really knows", I feel that we (humans) long for another species that is "on the same wavelength" as us. Think of it as belief. Not everyone believes the unknown the same way, and can cause conflict. With that said.....To me chickens are still more primeval. They rely on their instincts rather then feelings (whether they have them or not). The also are supported by their "pecking order", that can include other species as well as chickens......there has to be a "leader". We (humans) have "domesticated" the chickens for our use. If they were in the wild...you would not be able to get near them, but if you did they would run (unless cornered they might fight). If you tried to take a wild chickens egg, then you would be disturbing the nest and the hen would most likely not come back. The domestic chicken, however, is accustom to humans and human hands removing their eggs. Also, We have breed some of the instincts out of some breeds of chicken. Take the Leghorn, Sex Link, and other production breeds for example......Majority of the hens will never go broody or raise chicks.....there is always an exception. Chickens will also turn cannibalistic, even on their "friend" if certain occasions apply, and they continue with their lives like it never happened. Maybe saying that they don't have "human like" feelings is actually more like they don't have a conscience "like humans". We tend to live our lives on or morals, values, and such. This in a sort gives us or conscience...a way for use to tell "right from wrong"...in the "animal world" this would most likely get you killed. Some animals have been noted to show "human emotions" (mostly mammals...go figure). All in all....if you want to think that your chickens get sad, by all means you can believe that, but if you try to state it as a fact that might start a fight. I don't think they get sad, and that animals are animals.
There I go, fixing to get completely off subject.
But I don't believe they get say if you take their eggs, some want even notice and the ones that do see you as dominate.
