I looked at getting a cockatoo and believe me they are very needy birds. If you want a bird that needs to be with you constantly then a cockatoo is for you. They are a huge commitment that take a very special kind of person who can give them an abundance of one-on-one time. It is not a commitment that I could make. Please do a lot of research before deciding to purchase one.
Ana Grey used a sleeping tent this last winter but I have taken it out for the summer. She is only a year old now. I will put in back in in the fall/winter and see if she likes it. I don't cover my fids at night as I am a late riser and they enjoy the sunshine when it comes through the windows in the AM.
It is my understanding that a new oven or that type of appliance must have the toxins burned off before you use it. There should be a manufacturer's book with a new appliance with instructions on how to burn off factory toxins as well as proper venting instructions before using the oven/appliance. When you do this your birds should be preferably outside or in a very well ventilated area where the fumes cannot reach them.
I don't mix my fids' food together. There is a place for seed and nuts, a place for pellets, a place for dry vegetables and a place for wet foods (fresh vegetables or fruit and other wet foods). And of course the water bowl!
