Can hens be aggressive?

First off.....


Are you sure Hannah is a hen? She obviously doesn't crow right? It is possible for a hen to become aggressive. Since you do not have a rooster, she may be taking the place of one by being the dominant hen. Pics would be helpful so that we can make sure. The only way I can think to help stop her is to show that you are the dominant one. Do not be afraid of her. If she comes toward you, try chasing her back. Do stuff that would make her feel subordinate to you, but will not severely hurt her. Something that I've heard for younger chicks is to hold them until they stop making a fuss, then let them go when they settle down. This is to show that you are the boss.

 

First, as Year of the Rooster asked: Are you sure she's not a Rooster? I'm guessing if you are getting eggs then you know for a fact that she's a hen.

Yes, a hen can be aggressive (not usually with quite as much flair as a Rooster), I've got one hen that thought she could chase me around. I stopped it real quickly by moving directly into her 'charges' and picking her up. I then carried her around for a while, until she completely submitted to me, petting her and just talking to all the chickens while carrying her. After a couple of times of not allowing her to try to peck me (charge me) I've never had her try to mess with me again.

If you are afraid of picking her up (it can certainly be scary and hurt if you get pecked) wear some gloves and long sleeves. Keep her away from your face and don't let her know you are afraid of her.

Good luck - you need to stop this behavior right away.

 

Normally, roosters have this problem. But hens can be aggressive, too. Some are aggressive only when they are sitting on eggs(broody) and they can get mad and peck if you try and steal one! But some breeds, such as the rhode island red(that's one that tends to be bossy, male and female) are usually aggressive. So your hen isn't a rooster most likely. She is just aggressive because of her breed I think. Just carry her around and talk to her, and show her that you are the boss. She won't jump at you like a rooster does, but she will peck and bite to defend herself.
Good luck! And if you plan on trying to get over your fears of her, I would wear long sleeve pants/shirt and maybe some gloves, that way she can't really hurt you by pecking. But don't worry! Just be thankful that she's not a RIR rooster, like we have. He is usually aggressive, but we carried him around a it and he stopped chasing us as much as he did.

 

I have 3 hens who are very aggressive with our other 3 hens. Is this normal? Should I be concerned about our other hens? None of them are aggressive toward humans, we socialize with them quite often. Any advice is appreciated.

 

Yep hens can be downright awful mean Marlene my delaware mutt showed me that first hand. If she didn't lay the nicest eggs and chase squirrels she might be in trouble.

 

I couldn't get your picture to enlarge to examine your chicken closely. Yes, occasionally you will have a hen assume male characteristics in an all female group. She becomes dominant and bossy toward the flock just like a rooster would. And you will see aggressive behavior toward humans with poultry who think they are just as good as humans. If you have small children, I would place this 'hen' in another flock with full disclosure as to her temperament.
