First of all, any parrot keeper should ask himself why do parrots pluck their feathers. There are many different reasons for this nasty habit. The African grey parrot is a parrot species that need quite much attention from his human owner. If this doesn't happen then the bird will probably get bored and this can result in feather plucking. But believe me that this feather plucking problem is very complicated because it's very hard to resolve it.
There were cases when the African greys plucked their feathers because of getting too much attention. So you just don't know exactly how to treat your bird. Dietary imbalances or environmental problems may also take to feather plucking. Some environmental problems could be smocking very much in the room where the parrot is kept or keeping him in a space with dry air. Also is recommended for African grey parrots to get regular baths or to be exposed to some kind of moist air. The African grey parrots shouldn't encounter any frightening experiences because this can take to feather plucking.
If this nasty habit appears in your bird's daily activities than you should first see a veterinarian. He will probably try to find a physical explanation for the bird's problem. It's best to try to understand what the veterinarian explains and try to find some ways of resolving the problem. It is proven that the African grey parrot is the most intelligent species. His higher degree of intelligence, along with possible incorrect early socialization at the breeders and not understanding the bird’s intellectual needs when it becomes a companion parrot often leads to neurotic habits -- such as plucking.
Timnehs African grey parrots don't pluck their feathers as much as the Congo African grey parrot. This could be because they were not as popular as the Congo African parrot. Because of their duller coloration, they weren't as licked as the congo.
In conclusion, the feather plucking is a major problem for the African grey parrots because they are very difficult birds to take care of.
