hi! I recently rehomed a 10 year old grey. She was owned by an elderly couple and first for her entire life. Then a young couple bought her and rehomed her because the bird only liked the husband and it was the wife’s pet. I was told she liked the elderly couple equally however I know that’s hard to believe for a grey. I’ve had her about a month. I solely feed her and care for her. She is very aggressive toward me. She actually strikes at me and flies out of her cage sometimes when I just walk by bc she is scared. My boyfriend came over and she bonded with him within a few hours. It’s been weeks and they are inseparable. Is there nothing I can do to bond with her? Is she a bird that likes only men? Any tips or advice. Thanks.
