No peacocks will not kill chickens.
In fact they are quite gentle creatures and are actually quite afraid of chickens.
However if a peacock feels threatened by a chicken it may attack the chicken in order to protect itself.
Why Would A Peacock Kill A Chicken?
A peacock might kill a chicken for a number of reasons.
Peacocks are carnivores so they might simply be hungry and see the chicken as a potential meal.
Peacocks are also known to be aggressive animals and they might attack the chicken out of territoriality or simply because they don’t like the chicken.
It’s also possible that the peacock is simply acting out in frustration or anger and that the chicken is simply an unfortunate victim of that.
Whatever the reason it’s important to be aware that peacocks can be dangerous animals and that they should be treated with caution and respect.
