I am a new grey owner as of sunday(:. She is very sweet and shy so far. I m taking it slow of course, but I am still pretty new. I know they need stimulations so I bought her some cardboard chewing toys. The Lady who I bought it from warned me she could get aggressive from chewing because she might start nesting. Especially since it s spring, but I want to keep her occupied when i m away. I spend about 4-5 hours a day with my birds. Have you had a problem with nesting and chewing? Thanks
