LOL, that was VERY funny but I was kind of expecting this
It is not easy to deal with feather plucking. You think the problem is over, and then all of the sudden s/he starts plucking again. It is very discouraging for the owner and also puts a lot of unnecessary stress on a bird because each plucked feather has to be replaced.
That list I gave you is long, I know, but I'd suggest starting at least with the following:
1. Completely eliminate peanuts and sunflower seeds and that includes not just whole nuts/seeds but also crushed, so reading ingredients on a label is important.
2. If possible, start taking Goofy outside on a regular basis, weather permitting of course. He, especially needs real sunlight.
If it is not too hot, let's say max 75 F, let him stay in a full sun to make sure he does not go in a shaded area. If it is warmer, then you need to provide some shade.
They sell those inexpensive tiny cages in pet stores (for finches/canaries
). Such a cage would be OK for half an hour to an hour of staying outdoor. Or you could check Craigslist to find a bigger not expensive cage.
3. A warm spray bath (or a bath if he prefers one) every day. Plain water is the best if the plucking is not too serious or maybe consult your avian vet what s/he thinks about using AviX Soother on Goofy. It is a water based spray with pure aloe vera.
One of the last issues of Bird Talk magazine had short stories about birds who pluck feathers and about their owners - how they deal with the plucking problem. Most of them said that the important thing was to just accept the fact that their bird was a plucker and not to stress too much about it, because that is the last thing you want to do, to add more stress to already a somewhat stressed bird.
I promise, no more long lists
Lots of little hugs to Goofy.
