As some of you may know, I'm looking to get an African Grey as my first bird sometime this year in late summer/early fall. I'm now wondering which gender I should choose. Are there many physical differences as far as looks/size between males and females? Most importantly, are there many differences in temperament between males and females? I know this will greatly vary between individual birds, but if there's anything that is a general rule of thumb between males and females I would love to hear about it. Thanks!
