Yes pin feathers. Misting with a spray bottle ( that has never had anything but water in it) will gave him looking even more beautiful quickly. Offer a shallow dish for bathing and splash around in it with your hand , mist Quakers love baths!! Plus they need them! With the heat on your house my be to dry. If he let's you preen them off that's great too.
YUP-They start with a blood supply which will recede as they mature. The whiter ends will peel off and expose the feather a little at a time. Sometimes they are sensitive, other times, itchy. If you help preen them, make sure you don't break off part connected to blood and only help with the ones your bird can't reach (if bird is willing...this is optional).
