Welcome! You also need to remember that Grey time and our time are very different. A month to us may seem long enough to make a big change, but to a Grey that may seem like a day. SO, in working with Archie, please take your time and then some. A year is not too long to work before seeing a big response. BUT that said - it is SOOO worth the effort. A good diet, which you have started on. You might want to include some fresh vegetables in now. You said he likes the kitchen tap - does he 'shower' under it? If so wonderful! If not, you miay want to find out if he will. A shower a few times a week might help with his chewing the feathers - it might not but it is worth trying. If he doesn't like the tap try spraying him or maybe he would like a bath not a shower. Of course, if he is like most Greys, he won't like any of it - but you have to bath/shower him anyways! LOL
