Single birds that are hand tame if you place them in a cage with another bird then you may find they prefer to be with the other bird rather than you.

As for the black spot i would get it checked outr by an Avian vet as it could be mites or something more serious, It may just be nothing but its best to get it checked out.

Signs of illness are sitting fluffed up either on the cage floor or sat on a perch in a corner.
Not eating and drinking, Watery poop.

An avian vet will be able to take samples and have them checked out fully.
