My daughter and I have been blessed with two African greys. They are 18 and 16 years old. Both came from the same owner who raised them since they were babies. The male was very friendly when we meet him at his home. The female was very shy! Three weeks later, she has become a very loving bird! She loves interactions, stepping up and will even walk the house looking for us. She talks and talks!
He has changed and refuses to step up. When we approach him, he fluffs his feathers, puts his head down and will lunge to bite if pushed. This makes going into his travel cage very difficult. He will take treats and food from our hands. If he flies to the floor he will step up without any hesitation.
Any advice?
