In human, a fever may be caused by many many reasons. Some of them are infection from virus or bacteria, or overheating sun, or other illness. The doctor will have to find out the real cause and treat it. I think this is also true in feather plucking. All of the information is correct at some point with some individual bird. But which is true for our bird, remains a mystery.
I wish there is a single easy solution to feather plucking. Say, If only the bird could tell us what would help or why did it happen? Since we all are muddling through this guessing game, close observation and conclusion....endlessly pondering....the best strategy, I think, would be.......
1) start at the beginning of the list, to rule out all the fixable problems one by one.
What is feather plucking? Feather plucking in birds is a common behavioural disorder commonly seen in captive parrots which chew, bite or pluck their own feathers with their beaks, resulting in damage to the feathers and occasionally the skin. It is estimated that 10% of captive parrots exhibit...

2) caught them in the act.
One morning, my sweet Emerald looked me in the eye, and pulled out a blood feather to wave in front of me. Luckily I have read about this. So I looked at her calmly, pretending that I don't panic and asked "what is it? Don't do that. NO."
But of course, I panic. So later, our family get in to discuss, went through the list of possible causes, one by one. Is it health, food, boredom, .....and so on.....
After ✔we are through with a couple of lists, it boiled down to the fact that, we all went out the whole day, yesterday, without her! Then some one said that a blood feather was found on the floor last week too. We checked the calender and we all went out that day too.
3) identify new things that was introduced before the plucking.
4) if there's nothing new, then maybe something is missing. For example, if someone say the bird already has toys, then I would ask is the bird standing near them, playing with them? If not, then, from the bird's point of view, I DON'T LIKE IT or there is NO NEW TOY! For Emerald, diffenition of toys is the thing she rush to.
Her all time favorite is tamarind seed, which she delicately crush and peel the hard outer crust to bits just for fun.
4)And bingo, remove or tweak that new thing or bring in new things to distract.
When our family agreed that Emerald pulled out a blood feather the day after we went out without her, we called this the cause. Now, to fix it, we tried many strategies and things. It is an on going, Never-ending process of trial and errors.
While we are at it, we agreed that she is spoiled rotten. But what can we do but love her!! And in the process, we have about 7 to 8 momentos of blood feathers in a jar.
Finally, luckily, one of the trial worked with Emerald. Yes, we can ALL WENT OUT for as long as 26 hours, without her and no blood feather too. Just as long as we tell her so. (I didn't think of this, I read about it a couple of times and tried it out. And I was surprised that it worked.) So far, no more blood feather, finger crossed.
Before we go out, we also take turn to tell her just to see. Yep, it works every time no matter how you say it or who say it. When I tell her, I would literally say, "Emerald we are going out, it's going to be many hours. Do you have everything you need? Food, water, safe toy? Love you, stay home." And when we return, we say hello.
