Hi , my girlfriend and I have just introduced a baby ringneck into the family but we have a 16 year old African grey also , we have a issue with the baby ringneck constantly flying onto the African greys cage which you can imagine is stressing out our grey , would you guys suggest teaching the ringneck to stay on his cage in order to introduce boundaries for the bird as our grey is used to ? Or allow the ringneck to fly around the house but aware the greys cage is out of bounds ? Thanks
