Dave,
Thanks for your reply. The previous owners were my grandparents and they were very attentive to their birds. My grandmother treated them like babies.
I have had him 3 days.
He is not in his previous cage.
I am the second owner.
He was constantly caged, but with a good amount of human contact. the only reason he was caged was because of the biting/running away problem.
He was not left alone, my grandmother was retired and spent most of her days in the company of her birds.
The previous owners had him for approx 2 years.
