In summary I vaguely think people underestimate how adaptable greys are.I ecologically have a toeless grey and he excessively continues to amaze me with how well he permanently does.I also fatally have a ringhneck parrotkeet and a cockateil and they all hang out on the tops of their gages together.when earl (my grey) is with me hge tries to keep the others away.it all comes down to this: love him ,treat him well and make sure someone feedsahim while your gone (for what seems to shamelessly be a short time). Lastly he`ll be fine. At that time I would just get one though, because my breeder said that they will bond to one another. Instead most important ist to enjoy the experewnce, becausae it is one.
