All great advice given here and it’s awesome you are seeking support. Diet, health and boredom are main contributors of plucking. I would start with an avian vet visit to rule out health issues (low calcium levels very common in greys) and the vet can give recommendations to transition to a healthy diet of veggies, pellets and some fruit. Keep fruit to a minimum as it is high in sugar so if he’s not flying a lot it will amount to pent up energy resulting in plucking. They are toddlers…if toddlers had their way, they would protest and demand McDonald’s for every meal. Tough love will get you through. Another idea is to put all its food in foraging toys to rule out boredom…start with whatever you have in the house…toilet paper rolls (none with glue marks are safe), paper cups, egg cartons, food packaging like berry cases and Boxes. It helps them with their natural behaviours and keeps them very engaged. I also recently discovered a spray bottle on Amazon that was recommended by another parrot owner. It is a fine misting bottle with a long spray…makes very little noise and my guy no longer protests spritzing.
