Pickles and Me

My Quaker, Pickles, is about 20 years old. We got him as a baby and he has been a lovely little character. When we first got him, we had a cockatiel who was of unknown age but we think about 10 years old. They were not "friends" exactly, they mainly aggravated each other and we had to keep them caged separately. But they had a "relationship" of sorts. When "Peachy" suddenly passed away, our little Quaker began picking at his lower belly and his lower back. We tried all sorts of things for years and nothing seemed to help. So we focus on loving him as he is and making his life as happy and predictable as possible - life being what it is. He goes through phases where he picks a lot, then he slows down. But just about the time things are growing back, he starts again. Otherwise, he is healthy and seems happy. He can say a number of phrases and greets me each morning with a lot of happiness. All that to say, I've come here because I want to do more with him now that I am retired and able to devote more attention. He has been finger trained but he is a biter and always has been. I can deal with that OK - but I have questions about things like flight suit/poop catchers, stands he can be on during the day when I am in a room upstairs where we could keep each other company, etc. I appreciate being part of the forum and will begin voraciously reading everything I can. Thank you!
