I'm all for acknowledging the instinctive nature of chickens, but the fact is that for an animal (be it domestic, wild, or tamed wild) that is kept in confinement, one of the biggest effects on behavior is the environment that they are being kept in. This includes housing, ranging areas, diet, and husbandry practices. Therefore, it is logical that the OP would come searching for a reason for her bird's behavior that is other than "the underlying nature of chickens". Because there are so many factors that effect behavior, it isn't unreasonable for others to suggest that changes to housing set ups, space, diet, etc. are logical first steps to attempt to solve the issue.
I am a dog trainer. I work with dogs that are fearful and fear aggressive and in some cases have bitten other dogs and people. Yes, sometimes the best and safest answer is euthanasia, but sometimes a change in how the dog lives and is cared for can be the difference between an owner having to put their dog to sleep or that dog getting to live out its days as a cherished pet. It would be unethical of me to recommend that every dog that shows aggressive tendencies be euthanized without exploring other possibilities as the cause of the behavior. I had a client come to me for help with aggression. I recommended a full health check with bloodwork for their dog. Turns out he was suffering from hypothyroidism. Medication and some management changes mediated the problem. Another client's dog uncharacteristically bit a visitor. Circumstances pointed to a pain response. A health check indicated hip dysplasia, arthritis, and inflammation. Since being treated, the dog hasn't exhibited any more aggressive behavior. Should I have recommended they be euthanized? Most people would say not. Should I have chalked it up to "the underlying nature" of those dogs. No, the problem wasn't the dogs' temperment, breeding, or instinctive drive and to accept that as the only cause without exhausting other options would have been wrong.
