african grey parrot

Question
My african grey parrot has been losing a lot of feathers each day.  His chest and legs have no feathers on at all.This has been happening for about the last 4 days.

Answer
This sounds to me like his is plucking his feathers. This can be from a lot of things. Please visit my page on plucking.

Make sure you have shred-able toys in there to keep his beak busy. I would also get him to the vet and have him tested for PBFD a beak and feathers disease.
