Mean Hen

I have a hen that attacks all the other hens and killed most of them, can I train her to be nice? Jay

The only way I can think of is by adding Garlic and a nice red wine

Invite her to dinner.

Mean hens make nice soup.

In a flock of hens only, often one hen will take on the role of dominance. This dominant hen replaces the missing rooster, looking out for the flock as best she can. Overaggressive behavior is not uncommon. If your hen has killed other hens, I'd say you have an extreme case. Left with the remaining hens, you are likely to lose more. Cut your losses.

Coq au vin.

If she's killing other hens now, what can you expect if you add chicks as replacements?

if you don't want to eat her (I know when I have chickens they will be pets and not food but I understand many would eat her), you can remove her form the other hens for a few weeks and then they will develop a new pecking order and whens he returns she should be as a new chicken sort of at the bottom of the line and they will pick on her not the other way around. Also my understanding is good roosters will not allow any bullying amongst the hens so if you live someplace that roosters can live you might want to get one. A good rooster will also point out the best food to the hens and watch out for predators and warn them if any are about and also they act as alarm clocks.

we dont have pets, we have employees*.
if one of the employees is acting in a way that disrupts the group from doing their job, that employee must go

in your case i would suggest chicken noodle soup as she isnt likely big enough for a broiler.
if you dont want to eat her, you can try to give her away, and maybe she wont be at the top of the next pecking order. i have seen people giving away mean/old chickens away on craigslist, and i have given a few unwanted roosters away that way as well.



* but i totally understand chickens as pets, ours started out that way
