I have recently rescued a twelve year grey named Timmy. He is very sweet, but sometimes can be very aggressive and I need advice. His last owner, who got him from an unscrupulous breeder, who was only concerned about lining his pockets and failed to educate his last owner as to the perils of parrots entering sexual maturity. He screams and Sure, they are great when they are young and easy to manipulate and control, but once their hormones kick into overdrive - look out, because you are in for a wild ride. His last owner couldn't handle him anymore and she couldn't find a rescue to take him, because they are all filled to capacity. He is now my responsibility so I am going to keep him aggressive hormonal behavior and all, but I need to know if and when the end of an African Grey's sexual maturity can be expected. Thanks, Gloria
