hello there im in need of help here, i brought my African Grey at 8 years old yesterday off this male owner, he had about 3 African Grey but had pushed this one to the corner, whenever a male goes by him he makes a squawking sound, but when a woman goes by him hes okay, he doesn't bite at all, but my dad and boyfriend are not allowed by the cage and they want to mingle with him too as they like African Grey, also because his last owner never paid any attention to him and didn't give him much care he doesn't talk, do you think there's any hope for him to not squawk at men and also get talking? pleaseeee help me lol thanks guys, much apprechiated
