How to tell if your grey is molting or plucking.

[snowkatt]

My baby is about 1 year old he always had the most beautiful feathers but now he looks rather scruffy I'm very paranoid I am doing something wrong. Hes my first african grey so any advice would be appreciated. He is so very sensitive , I have tried misting him in the shower he hates water. He wont even eat vegetables or fruit in the whole form I have to puree them and make him smoothies everyday. I need to know the difference between molting and plucking and what I should do.
