This is some really terrible generalizing. I've spent a lot of time with a lot of different chickens (hens and roosters). If you spend a fair amount of time with them, you really do see individual personalities strongly emerge. I've known many chickens to learn their names and excitedly come running up when called. I've also known a few who enjoyed being held.

Now, I've also spent some time with ducks and I'm not going to do any sort of contrast like you have. Ducks can be just as pleasant to be around. They can also be horrible to each other. I knew one duck who was prone to getting picked on by his flock mates, who occasionally attempted to drown him.

I've gotta laugh a bit at your use of the word avaricious to describe a chicken. I'm not sure where that could even be coming from. I'm not trying to discount your experience, but it really doesn't seem to me that you spent the time getting to know the animals in any way. And using that as a justification to eat them. Well I've got some coworkers you might be interested in too...
