Budgies can't pull out feathers that they can't reach with their beaks. If a bird is losing feathers on its head or neck, the problem is not plucking (unless a cagemate is responsible for the plucking). Bald spots are not normal for budgies, even elderly ones. You should consult an avian veterinarian.
Your, budgie may be suffering from an unknown disease, seek medication for it ASAP.
Definitely! If a budgie has dull feathers, it may not be getting proper nutrients, but if it has feathers that look like a sickly greenish-brown color, it need WAY more water. it may being poisoned with too much nutrients. DO NOT over-feed these things But, yes. If your little Budgie buddy has colorful feathers, and seems to not lack energy, he is the picture of health! Have fun with your Budgie!
Prolly means your budgie is sick, please take to the vet.
About 1-2 weeks
It means they are stretching the feathers in the tail
ofcource
Pink feathers attract love.
When its itching more then usual or rubbing its head on a perch (watch for any kind of mites though or a skin condition) and when it looses some feathers (not patches though,then your budgie maybe pulling them out or a cage mate might be)
On a A young budgies head, it will have striped feathers going all the way to its nostrils. As the bird matures these feathers get replaced by plain feathers, they will be replaced about as far back as the eye.
Not at all. No Australian native birds hibernate. If your budgie is sitting with its head buried in its feathers all day, it is either too cold for the bird, or your budgie is sick.
It is not unusual for a budgie (parakeet) to molt in the winter. You might want to watch out because usually they are cranky when they molt! (But they like having those itchy new feathers to be scratched)
Usually until it gets all of its feathers.
