Welcome to the Community! Please do not ever hesitate to ask ANY question you may have, because with birds there are definitely no stupid questions!!!
As Noodles wisely mentioned to you above (new bird owners may not know anything about the danger of any scents/fumes/smoke/odors) if you own/use any pots, pans,
or bakeware/cookware that has a non-stick coating that contains any Teflon and/or any of the lethal Fluorinated Compounds such as PFOA, PFTE, etc., you must not ever use them in your house again now that you have a parrot! Usually these lethal non-stick coatings, when it comes to pots and pans, are black in color. So if your pots and pans have a black non-stick coating on them, then they're most likely going to have to be replaced; however, even if they aren't black coatings, that doesn't mean they are safe, you must confirm this...Instead of using these very common types of pots and pans, you must use either Ceramic Non-Stick, Stainless, Cast-Iron, or real Copper...
Also, you cannot ever run the "Self-Cleaning" cycle on your oven; you'll have to start cleaning your home with unscented, natural cleaning products; most of us use a mix of White Vinegar and very Hot Water, or we buy unscented, plant-based cleaning products. You can't use any type of "scented products", like any that you plug-in to emit scents, no candles of any kind, no incense, no scented oils (not even essential oils, they are not safe either), basically nothing scented. Birds are extremely sensitive to any and all scents/fumes/odors/smokes, and even your perfume can make your Nanday extremely ill or worse...The Teflon and Fluorinated Compound coatings emit lethal fumes that usually kill bird instantly. So it's really is a matter of totally changing the way you clean your home, and the way you live inside it, if you're a person who likes to burn candles or use any type of scented products...
How old is your Nanday? Did you get him from a breeder, pet shop, etc.? Or did you adopt him? The reason I ask is I'm wondering what his regular, daily diet is/has been, because their diet is so very important, and a diet high in fat is one of the main reasons that pet parrots die young...What is his daily diet?
