How much should the minimum cage size of the african grey parrot?
That would be the minimum I would get I would try to get it wider. My grey loves to explore in his cage I have a bungee and three types of perches and three or four toys which I change. If you leave you grey during the day I would get larger cage. Because a one time expense is better than your baby pucking his feathers from being bored. Make sure no matter how big the cage you give him time outside the care. I try to take mine out 4 to 8 hours a day. Some days I am unable to do this when we go visiting. Make sure you have one toys he can destroy and take it out when it get ragged either trim it up or fill it up.
