First let me say that I am a chicken newbie (although I have experience w/ parrots) and I was reading the post "When do roosters turn vicious?" Am I trying to associate a human characteristic, jealously, to chickens? Also, this is from a pet chicken owner's perspective (so a lot of individual attention is given (eg. cooing to the pets).

In general, do they seem to be mean when they see attention given elsewhere that they would prefer given to themselves (and then punish the poor recipient), or do roosters just "punish" others that they observe and perceive exhibiting a "rooster" behavior?

With the chicks, it seems that they respond to affection and do get jealous. But I'm wondering about the adults. Thanks!!!

note: I noticed that parrots do seem to respond to jealousy. They remember and react angrily at a later time when "wronged". Also, you really can tell when a parrot is angry!!!
