Chooks, I dont, haven't, wouldn't and will never abuse an animal, most definitely not my baby chickens, but I cannot and will not allow her to think that drawing blood and coming back for more is a good thing to do. The worst I have ever done to reprimand her is when she had a hold of my finger one day I gently pinched her on the comb thinking it might have the same effect as when the other hens do this to her if she is out of line with them, or to gently shove her out of the way while telling her off.
I wouldn't re home her either as she is fairly old and is a rescue hen, so she's been through enough and settled in her home with the other hens, I don't think it would be fair to move the problem on as such.
The only reason I suggested you rehome her is because it sounded like you thought it was only a behavioral problem, not anything else, in the previous post.
I've dealt with hens like her before, which is why I gave you the suggestions I did; you can't fix that mindset with training alone, because it's based on nutritional deficits. As long as she's looking for food everywhere, and you don't both provide better nutrition and help her learn where to get it and where not to get it, the problem will continue.
Humans with pica are every bit as logical as chickens with pica --- not at all, big brains notwithstanding.
I'm not sure it is as simple as Pica as she's not going round pecking everything in sight, it's mainly pecking at me, my clothing or at other people and she really does need to realise that I'm the boss lady around here.
A common expression of pica is attempting to consume living creatures of non-prey types like humans and other chickens.
Certainly she's not trying to eat your clothing because she's mentally normal, lol, surely you agree with that.
It's an aberrant mentality caused by a lifetime of malnutrition. It's why cannibalism is so common in them, it's all hand in glove. Chances are she's committed cannibalism before, (possibly only on a minor scale like ripping out feathers and eating the blood filled quills) --- which reinforces the behavior --- but when the mind is aberrant, trying to retrain it like it's rational is of course just going to fail, because it's a derangement and they do not respond to reason.
Like Island girl says I can cope with a little cut or a nip or two but the local kids might not be so lucky if she gets a taste for human blood.
She already has a taste for blood. Only helping her nutritionally is going to settle her rampant cravings. Training will help keep her at a distance but won't stop the cravings, and won't make her stop looking for fresh nutrients.
You will have to keep the kids away from her if you want them safe, that much was already obvious. In the long term to make her safer more than just training will be needed.
Island girl is talking about retraining chickens with bad social manners, not dealing with chickens with pica, it's not the same thing at all.
My girl does love me, she is the first to come running up to see me when I open the house door and often just lies at my feet and purrs, but maybe that's part of the issue, maybe she needs to realise where she is in the pecking order around here.
At no part in a normal chicken hierarchy is drawing blood by biting and attempting to consume one another a normal behavior. They do not naturally behave like that, it's NOT dominance behavior at all.
The comment about abuse was intended to refer to the fact that you can quite literally abuse an animal and it still won't change a non-rational behavior, whereas abusing an animal can change deliberate behaviors because it will be far more likely to connect cause and effect.
At no point did I say anyone was abusing chickens, lol, and obviously it should go without saying that I don't condone such behavior.
All I meant is that applying logical training to an illogical behavior is obviously unlikely to work, because it's not the same as applying training to a deliberate behavior.
I personally don't believe in trying to take the dominant chicken role, because I'm not a chicken, and my chooks respect humans as being automatically dominant without it ever needing to be physically enforced, which I believe is the natural state of things, but each to their own; I know not everyone shares that belief.
x2 on not placing food anywhere on the body to teach them NOT to peck you. That seems extremely counter-productive. Chickens are not dogs and methods that work well for one may not work for the other.
While it may seem counterproductive to you, I've dealt with numerous hens with pica, and the methods I mentioned worked in practice.
Chickens can be trained much the same way dogs, sheep, horses, etc... I've done it before, so while you don't think it will work, I know from experience that it will.
They are absolutely smarter than they get credit for.
I agree; but you cannot train an animal out of malnutrition nor mental derangement.
Best wishes.
